If the problem states that the time is a miss penalty, it should mean that the time is in addition to the time for a cache hit; so the total miss latency is the latency of a cache hit plus the penalty. (Clearly your formula and variables do not take this approach, labeling M--which …

WebMemory Access Time: In order to look at the performance of cache memories, we need to look at the average memory access time and the factors that will affect it. The 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 WebMemory Access Time: In order to look at the performance of cache memories, we need to look at the average memory access time and the factors that will affect it.
