What is ComputerMemory?
Introduction
Memory is where a computer stores data
and instructions.
It helps the computer perform tasks by holding
information temporarily or permanently.
4.
Why Memory isImportant
It lets the CPU access data quickly.
Without memory, the computer can't run programs
or store files.
It makes data processing fast and efficient.
Stands for RandomAccess Memory.
Temporary: data is lost when power
goes off.
Used for running programs and processes.
Primary Memory – RAM
7.
Primary Memory –ROM
Stands for Read-Only Memory.
Permanent: stores data even when
the power is off.
Stores important startup instructions
(like BIOS).

Types of RAM
1.SRAM (Static RAM):
Fast and reliable, used in cache memory.
2. DRAM (Dynamic RAM):
Slower but cheaper, used in main memory.
9.
Types of ROM
1.PROM:
2. EPROM:
3. EEPROM:
Can be written once.
Can be erased with UV light.
Can be erased and re-written
electronically.
10.
Secondary Memory
Usedfor long-term storage.
Slower than primary memory but
holds more data.
Examples:
Hard drives, SSDs, USBs.
11.
Cache and Registers
1.Cache Memory:
Very fast, stores frequently used data.
2. Registers:
Tiny memory inside the CPU, super-fast and
used for instructions.
12.
Memory in DigitalLogic Design
Helps in designing memory circuits using flip-flops and
logic gates.
Concepts like storage units, buses, and addressing are
based on DLD.

Conclusion
Understanding itstypes and structure helps in both
hardware and software design.
Strong memory systems lead to better speed and
performance.
Memory is a vital part of any computer system.
