Hybrid logical to physical caching scheme

Abstract:

A variety of applications can include systems and methods that utilize a hybrid logical to physical (L2P) caching scheme. A L2P cache and a L2P changelog in a storage device can be controlled for use in write and read operations of a memory system. A page pointer table in the L2P cache can be accessed, for performance of a write operation in the memory system, to obtain a specific physical address mapped to a specified logical block address from a host, where the access is based on the page pointer table loaded into the L2P cache from the L2P changelog. The L2P cache area can be progressively configured with the most frequently accessed page pointer tables in the L2P changelog in the latest host accesses.
