Cache Memory

Cache memory, also called CPU memory, is high-speed static random-access memory (SRAM) that a computer microprocessor can access more quickly than it can access regular random-access memory. This memory is typically integrated directly into the CPU chip or placed on a separate chip that has a separate bus interconnect with the CPU.
