Which chips are used for the implementation of Cache Memory?
A
DRAM
B
SRAM
C
Onboard
D
onchip
Explanation: 

Detailed explanation-1: -The cache memory is typically implemented with static random-access memory (SRAM), in modern CPUs by far the largest part of them by chip area, but SRAM is not always used for all levels (of I-or D-cache), or even any level, sometimes some latter or all levels are implemented with eDRAM.

Detailed explanation-2: -SRAM is commonly used for a computer’s cache memory, such as a processor’s L2 or L3 cache. It is not used for a computer’s main memory because of its cost and size. Most computers use DRAM instead because it supports greater densities at a lower cost per megabyte (MB).

Detailed explanation-3: -The SRAM component of our hierarchical memory system is called a cache. It provides low-latency access to recently-accessed blocks of data.

Detailed explanation-4: -Memory caching is effective because most programs access the same data or instructions over and over. By keeping as much of this information as possible in SRAM, the computer avoids accessing the slower DRAM.

Detailed explanation-5: -The answer: A) SRAM Static RAM is commonly used for L1, L2, and L3 cache memory.
