What are the two types of cache memory?

Primary and secondary

DRAM and SRAM

Physical and virtual

Cache memory is used to reduce the average time to access data from the Main memory.

SRAM is an on-chip memory whose access time is small (fast).

DRAM is an off-chip memory which has a large access time (slow).
