Memory module for managing eviction of cache data, memory system including memory module, and method of operating the same

Abstract

The present technology relates to an electronic device. According to the present technology, a memory system includes a first memory module communicating with a host through a first interface and a second memory module communicating with the host through a second interface and having a tier lower than that of the first memory module. The first memory module comprises a memory device and a memory controller. The memory device may store cache data. The memory controller may store access pattern information of the host for the memory device, select candidate data to be evicted among the cache data based on the access pattern information of the host and a plurality of algorithms, and evict target data among the candidate data.
