In computer science, Average Memory Access Time (AMAT) is a common metric to analyze memory system performance. AMAT uses hit time, miss penalty, and miss rate to measure memory performance. It accounts for the fact that hits and misses affect memory system performance differently. In addition, AMAT can be extended recursively to multiple layers of the memory hierarchy. It focuses on how locality and cache misses affect overall performance and allows for a quick analysis of different cache design techniques. A tacit assumption of AMAT is that a data access is either a hit or a miss, meaning the memory only supports sequential accesses and cannot have multiple accesses occurring simultaneously. Recently AMAT has been extended to consider concurrent data access. A model, called Concurrent-AM
