Method and system for efficiently swapping pieces into and out of DRAM

摘要

A system and method for managing swaps of pieces of an address mapping table is disclosed. The method may include a controller of a storage device receiving a stream of requests for accesses to the mapping table, analyzing the stream of requests to determine at least one characteristic of the stream of requests, and determining whether to copy a piece of the mapping table stored in non-volatile memory into the volatile memory based on the determined at least one characteristic. The system may include a storage device with a controller configured to perform the method noted above.
