(c) DRAM

(d) SRAM

I got this question in final exam.

I'd like to ask this question from Cache Memory in division Memory Systems of Embedded Systems

Answer 1

Right answer is (b) Cache memory

To explain: The cache memory is a small random access memory which is faster than a normal RAM. It has a direct connection with the CPU otherwise, there will be a separate bus for accessing data. The processor will check whether the copy of the required data is present in the cache memory if so it will access the data from the cache memory.
