Cache Memory Description

Its of no doubt that the cache memory plays a vital role in a computer system. It is responsible for speed of the processor. Normally Cache memory is a special type of memory that is used by the microprocessor for speedy access of data. The cache memory is used to reduce the amount of time wasted by the microprocessor in waiting for fetching data. Cache memory may also be called as Random Access Memory(RAM). Cache memory are categorized into levels based on their associativity with the microprocessor. The Level 1 cache memory can also be called as L1 cache, these L1 cache memory is small and provides faster access to important and frequently used data. Normally the Leve1 cache memory will be on the same chip as the processor. The Level2 cache memory can also be called as L2 cache for short. It is slightly slower than L1 cache. These L2 cache memory chips are placed close to the processor to gain maximum speed. In addition to L1 and L2 cache memory the modern computer processors also use L3 cache for high performance.
