Memory module for prefetching 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 host, a first memory module communicating with the host through a first interface and a second memory module communicating with the host through a second interface. The host comprises a prefetch table storage and a map manager. The prefetch table storage may store a prefetch table indicating candidate data to be prefetched to the first memory module among data stored in the second memory module. The map manager may prefetch target data from the second memory module to the first memory module according to whether the target data is included in the candidate data when the target data requested by the host is cache-missed in the first memory module and is cache-hit in the second memory module.
