The shortest … WebThe average memory access time (AMAT) is defined as AMAT = htc + (1 – h) (tm + tc), where tc in the second term is normally ignored. h : hit ratio of the cache tc : cache access time 1 – h : miss ratio of the cache tm : main memory access time AMAT can be written as hit time + (miss rate x miss penalty). Reducing any of these factors reduces AMAT.
