A computer has two levels of memories, cache memory and main memory, with an access time of 0.01 µs and 0.1 µs respectively. If the hit ratio of the cache memory is 90%, which of the following is the appropriate average memory access time for this system? In this scenario, if the data is in the cache memory, the processor accesses the data directly with an access time of 0.01 µs. However, if a cache miss occurs, the data is required to be transferred from the main memory to the cache memory first, and then subsequently accessed from the cache memory. Thus, the access time becomes 0.11 µs.
