WebCache memory, also called CPU memory, is random access memory ( RAM ) that a computer microprocessor can access more quickly than it can access regular RAM. This memory is typically integrated directly with the CPU chip or placed on a separate chip that has a separate bus interconnect with the CPU. WebWhat is L1 cache? L1 cache is the fastest cache is a Computing system. It is exclusive to a CPU core and is also, the smallest cache in terms of size. L1 cache is of two types: Instruction Cache. Data Cache.
