RAM (Random Access Memory)
The document discusses the history and types of random access memory (RAM). It notes that the first form of RAM was cathode ray tubes in 1947, followed by magnetic-core memory in 1955. Modern RAM was introduced in 1969 by Intel. The document then describes different types of RAM including static RAM (SRAM), dynamic RAM (DRAM), synchronous DRAM (SDRAM), direct Rambus DRAM (DRDRAM), and video RAM (VRAM). It provides details on the characteristics of SRAM and DRAM such as data volatility, refresh operations, cell structure, read/write speeds, cost, and applications.
Types of ram
Random access memory (RAM) is a form of volatile computer memory that allows for quick reading and writing of data. RAM was invented in 1947 using Williams tubes, then improved with magnetic core memory in the 1940s-1970s. Dynamic RAM (DRAM) stores each bit in a separate capacitor and needs periodic refreshing, while static RAM (SRAM) retains data without refreshing and is used for computer caches. Both DRAM and SRAM are now integrated circuits with DRAM primarily in personal computers and SRAM in computer caches.
Types of ram
There are two main types of RAM: static RAM and dynamic RAM. Static RAM retains information without refreshing and can operate at high speeds, while dynamic RAM is used in most personal computers and requires refreshing to retain information, making it less expensive but also less powerful than static RAM. RAM is a type of volatile memory used in cache and registers.
Dram and its types
This presentation discusses Dynamic RAM (DRAM) and its types. It begins by explaining what RAM is and how it provides faster access for the CPU than the hard disk. It then covers that DRAM is the main memory in computers and must be refreshed periodically to prevent data loss. The main types of DRAM discussed are SDRAM, DDR, RDRAM, and DRAM memory modules. Specific details are provided about the features and operation of each DRAM type. Major memory manufacturers are also listed.
Types of ram
There are three main types of RAM: Dynamic RAM (DRAM), Static RAM (SRAM), and Magnetoresistive RAM (MRAM). DRAM stores each bit in a separate capacitor and transistor, while SRAM uses multiple transistors per cell without capacitors. MRAM uses magnetic charges instead of electrical charges, providing greater storage capacity, lower power consumption, and faster access times than other RAM types. RAM technology has advanced from SDRAM to DDR1, DDR2, DDR3, and now DDR4, with increasing speeds and capacities over time.
Random access memory
RAM is a form of computer memory that can be accessed randomly; it is volatile, meaning stored data is lost when power is removed. RAM was invented in 1968 by Robert Heath at IBM to function as temporary memory for processing data from permanent storage like hard disks. There are different types of RAM technologies including SRAM which retains data through static memory cells and DRAM which uses capacitors and must be regularly refreshed. RAM capacities have increased significantly over time from megabytes to gigabytes currently produced by various manufacturers. RAM provides faster program loading than hard disks but has the disadvantage of being volatile and space-limited.
RAM and ROM Memory Overview
This document provides an overview of different types of computer memory, including RAM, ROM, and hybrid memory. It describes the characteristics of SRAM and DRAM, the most common types of RAM memory. DRAM is cheaper and slower than SRAM, and must be periodically refreshed. The document outlines the evolution of DDR RAM standards and their internal structures. ROM includes mask ROM, PROM, EPROM, and is read-only memory that can be programmed during manufacture or special modes. Hybrid memory such as flash memory has qualities of both RAM and ROM.

Ram presentation
RAM stands for Random Access Memory and can be accessed in a non-sequential order. There are two main forms of RAM: SRAM and DRAM. SRAM is static and holds its data without needing to be refreshed, while DRAM must be refreshed regularly to maintain its data. DRAM is the most common type used in computers today and comes in different speeds and sizes, with examples being DIMM, SO-DIMM, and DDR memory sticks. Computer memory has a big effect on system performance.
Static and dynamic memories
The current technological revolution around the world has made the world faster with the
advancements in sophisticated computer devices. Computer, as a digital machine, enables people
to work faster than ever before. The memory of this device is a great feature of this digital tool.
RAM, Random Access Memory is the primary tool of data storage that is inserted in the
integrated circuit while data can be accessed in any sequence or randomly. Thus it is termed
RAM or Random Access Memory.
The journey of dynamic and static RAM was initiated in 1960s which can readily
developed in 1970s. Now a days the technology is much more user friendly. RAM is further
divided into three types:
• Dynamic RAM (DRAM)
• Static RAM (SRAM)
• Non-volatile RAM (NVRAM = RAM + Battery)
but we will discuss only first two i.e. (DRAM and SRAM).
Dynamic RAM is the most common memory used now a days. Inside of the RAM chip
there is a memory cell that holds one bit of information and is divided into further two parts: a
transistor and a capacitor. The capacitor holds the bit of information as a state of 0 or 1 and the
transistor acts as a switch that lets the control circuitry on the memory chip that reads the
capacitor or change its state. The capacitor is like a small bucket that stores the electrons in it. To
store 1, bucket gets filled with electrons and to store 0 buckets gets empty. The problem with the
capacitor’s bucket is that it has a leak and in a matter of few seconds a full buckets becomes
empty. Therefore they need to be recharged continuously in order to work properly and because
of this reason it has been given the name Dynamic RAM. This refreshing phenomenon is time
consuming as well.
In static RAM a flip-flop holds each bit of a memory. A flip-flop memory cell takes 4 to
6 transistors along with the wiring. Due to this reason they draws current all the time and gets
warm easily, therefore, they cannot be packed together tightly. They do not require any
refreshing method though, therefore, they are very fast memory chips.
RAM(Random Access Memory)
RAM, or Random Access Memory, is a type of data storage used in computers that is located on the motherboard and allows quick access by the processor. There are two main types of RAM: DRAM (Dynamic Random Access Memory) and SRAM (Static Random Access Memory). DRAM needs to be refreshed often and uses a single transistor and capacitor per bit, while SRAM does not need to be refreshed and uses an array of six transistors per bit, making it faster to access but more expensive than DRAM.
Random Access Memory
This document provides an overview of RAM (random access memory). It describes RAM as volatile memory that does not retain data when power is turned off. The document then discusses RAM components like SRAM and DRAM. SRAM stores bits using a flip-flop circuit that retains data as long as power is applied, while DRAM uses a capacitor and transistor that must be regularly refreshed to maintain its charge and data. The document concludes with a comparison of SRAM and DRAM, noting key differences in their data volatility, refresh needs, cell structures, speeds and costs.
Memory
1. The document discusses different types of computer memory including RAM and ROM.
2. RAM is volatile and can be written to and read from, while ROM is non-volatile and can only be read from.
3. RAM includes SRAM and DRAM, with SRAM being faster but using more transistors than DRAM. DRAM must be periodically refreshed to maintain its memory.
Ram and types of ram.Cache
The document discusses memory architectures including Harvard and Von Neumann architectures. It provides details on each:
- The Harvard architecture has separate memory for instructions and data allowing parallel access, but is more expensive.
- The Von Neumann architecture shares memory for instructions and data through a common bus, making it simpler but limiting parallelism.
- It also discusses memory types like RAM, SRAM, and DRAM and cache memory levels L1 and L2. RAM is volatile memory used for main memory, while SRAM is faster but more expensive and used for caches. DRAM is cheaper than SRAM but needs refresh cycles. Caches improve performance by storing recently used data and instructions from main memory.
Dynamic RAM
Asynchronous DRAM (ADRAM) is widely used due to its internal architecture and interface to the processor's memory bus. However, ADRAM has slow access times which degrade system performance. Synchronous DRAM (SDRAM) was developed to exchange data with the processor synchronized by an external clock, allowing full processor speed without wait states. Later, Double Data Rate SDRAM and Rambus DRAM were introduced to increase data transfer rates.
RAM
RAM is used for temporary storage of running programs. There are two main types of RAM: SDRAM and DDR RAM. SDRAM is commonly used in older PIII motherboards at speeds ranging from 66MHz to 133MHz, while DDR RAM is faster and used in newer P4 motherboards at speeds from 266MHz to 800MHz. Common RAM errors include failure to display with beeps, blank screen, misreported RAM size, and memory errors. These errors can be caused by incorrect configuration, installation issues, or faulty RAM. The solutions include confirming the configuration, checking the RAM installation, and potentially replacing damaged RAM.

Memory And Storages
RAM and ROM are two types of computer memory. RAM, or random-access memory, is volatile and used for temporary storage of programs and data that are actively being used. It allows information to be accessed randomly in constant time. ROM, or read-only memory, is non-volatile and used to store permanent programs and data. It can only be modified slowly or with difficulty. The two main types of RAM are SRAM and DRAM, while the main types of ROM include PROM, EPROM, EEPROM, and flash memory. Both RAM and ROM have evolved over time, with innovations allowing for greater memory density, faster speeds, and easier reprogramming.

There are two main types of RAM: DRAM uses capacitors and must be refreshed, while SRAM uses flip-flops and does not need refreshing. The document also discusses cache memory, ROM, EPROM, EEPROM, flash memory, memory organization, errors and interleaving.
RAM pppt.pptx
RAM, or random access memory, is the internal memory of a CPU that is used to store data, programs, and program results temporarily. It allows for random access of data. RAM is volatile, meaning data is lost when power is removed. There are two main types of RAM: static RAM (SRAM) which does not need to be refreshed but is more expensive, and dynamic RAM (DRAM) which must be refreshed but is cheaper. A limitation of RAM is that it is volatile memory, so all data is lost when power is removed.
Random Access memory.
RAM is the most common type of computer memory. It is volatile, meaning stored information is lost when power is removed. RAM is made up of small memory chips that form modules to store operating systems, programs and data for quick access by the processor. RAM was invented in 1968 and its capacity has doubled approximately every two years. Common RAM types are SRAM and DRAM. RAM provides faster access than storage drives but requires constant power to maintain data.
Ram presentation
RAM, or Random Access Memory, is a type of volatile memory that can be accessed randomly. There are two main types of RAM: SRAM (Static RAM) and DRAM (Dynamic RAM). SRAM does not need to be refreshed, while DRAM must be refreshed regularly to maintain its data. DRAM is faster than SRAM but also more expensive. DRAM is the most common type used in computers today and comes in memory module forms like DIMMs, SO-DIMMs, and memory sticks.

COMPUTER ORGANIZATION NOTES Unit 5
Memory systems can be classified as primary or secondary. Primary memory includes RAM and ROM. RAM is further divided into static RAM and dynamic RAM. Dynamic RAM includes synchronous DRAM and asynchronous DRAM. The maximum memory size is determined by the processor's address lines. Data is transferred between memory and the processor via memory address and data registers. Random access memory allows direct access to any memory location using its row and column address. Dynamic RAM is the most common memory type, using a transistor and capacitor in each memory cell to store data. Dynamic RAM must be regularly refreshed to prevent data loss from capacitor leakage.
