RAM is a type of volatile memory that is used as the main memory in a computer. It allows for fast random access to stored data. RAM was invented in 1968 by Robert Heath and consists of small memory chips arranged on a module. Data is stored temporarily in RAM when programs are opened, allowing for much faster access than reading from storage drives. The two main types are SRAM, which retains data as long as power is supplied, and DRAM, which must be regularly refreshed. RAM provides faster access times than other memory but has less storage capacity and is volatile.
RAM (Random access memory) is the place in a computer where the operating system, application programs, and data in current use are kept so that they can be quickly reached by the computer's processor.
RAM stands for random access memory. these slide are about ram. ram has two main types SRAM(static ram) and DRAM(dynamic ram). in these slides SRAM and DRAM are defined briefly. read and write operations of RAM, RAM size, RAM fundamentals and timing waveform are also discussed in these slides.
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) is a volatile memory.RAM is our working memory storage. All the data, which the PC uses and works with during operation, are stored here. Data are stored on drives, typically the hard drive. However, for the CPU to work with those data, they must be read into the working memory storage, which is made up of RAM chips.
Historical review:
Back in the 80's, PC's were equipped with RAM in quantities of 64 KB, 256 KB, 512 KB and finally 1 MB. Around 1990, advanced operating systems, like Windows, appeared on the market, that started the RAM race. The PC needed more and more RAM. That worked fine with the 386 processor, which could address larger amount of RAM. The first Windows operated PC's could address 2 MB RAM, but 4 MB soon became the standard. The race has continued through the 90's, as RAM prices have dropped dramatically. Today it would be foolish to consider less than 64 MB RAM in a PC. The OS like windows Xp requires better than this.

4. Introduction:
Random Access Memory (RAM) is the best known from of computer
memory.
RAM is considered as volatile memory, which means that the stored
information is lost there is no power.
RAM is made up of small chips that from a memory module.
Whenever you open a program, it gets loaded from the SSD/HDD
into the RAM.
This is because reading data from the RAM is much faster than
reading data from the SSD/HDD.
6. Technology:
Type Year
Fpm (Fast page mode) 1990
EDO (Extended data o/p) 1996
SDRAM (Single dynamic RAM) 1996
RDRAM 1998
DDR SDRAM 2000
DDR2 SDRAM 2003
DDR3 SDRAM 2007
DDR4 SDRAM 2014

7. Block Diagram of RAM:
This block diagram introduces the main interface to RAM.
A Chip Select, CS enables or disables the RAM.
ADRS specifies the address or location to read from or
write to.
WR selects between reading from or writing to the
memory.
To read from memory, WR should be set to 0
13. Types of RAM:
SRAM (Static Random Access Memory)
SRAM holds data in a static from, as long as the memory has
power.
Each bit is stored on four transistor that froms two cross
coupled inverters.
DRAM (Dynamic Random Access Memory)
DRAM is called dynamic because it must constantly be
refreshed and lose the data in very short time.
DRAM stores each bot of data in a separate capacitor within a
integrated circuit.
14. Difference:
SRAM DRAM
Requires less memory. Requires more memory.
Access time is low. Access time is high.
Do not refresh. Need to be refresh.
Faster access time. Slow access time.
More power consumption. Less power consumption.
Used in cache memory. Used in main memory.
16. Advantage and Disadvantage:
Advantage:
Program will load much faster.
Power Efficient that uses much less power then disk
drive.
Disadvantage:
Volatile: a power outage will cause irrecoverable.
Space-limited: cost per bit is high.
