Cache memory is a special kind of RAM known as the SRAM (Static RAM). It is quite fast and is used to temporarily store very active data and make this stored data available when the system needs it. Types of cache memory include level 1(L1) and level 2(L2) cache. L1 cache is the primary type of cache memory and is dependent upon the computer processor. It is used first by the CPU to collect information. If the information is missing, it jumps to the L2 cache which is the secondary type cache memory. It has a bigger capacity than the L1 cache
