Abstract
A memory controller includes a cache memory, a host control circuit, and a flash translation layer. The host control circuit receives a read command and a logical address from a host, reads out mapping information corresponding to the logical address from a buffer memory device, and caches the mapping information in the cache memory. The flash translation layer reads a physical address corresponding to the logical address from the mapping information cached in the cache memory.
