Description: cache n. a special cache memory subsystem, which replicated the frequently used data for fast access. Cache memory stores frequently accessed RAM locations and the contents of the memory address of these data items. When the processor references an address in memory, the cache will check if there is the address. If there is the address, it will return the data processor If you do not save the address, the routine memory access. Because cache memory is always faster than main RAM memory, so when the RAM access speed than the speed of the microprocessor, often using high-speed buffer memory.
