BYTE-ADDRESSABLE FLASH-BASED MEMORY MODULE, NVDIMM-TYPE MODULE, AND DATA STORAGE METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a flash-based memory module and an operation method thereof.SOLUTION: A method of storing data in a memory module 100 including an in-module prefetcher 200, an in-module prefetch buffer 160, memories 150a-150z, and a memory controller 140, includes the steps of: sending address information from the in-module prefetcher to the memory controller and to the prefetch buffer; determining prefetch accuracy based on a comparison of the address information sent to the memory controller and the address information sent to the prefetch buffer; determining a prefetch mode based on the prefetch accuracy; and storing the data in the memory based on the prefetch mode.SELECTED DRAWING: Figure 1
