Sequential-write-based partitions in a logical-to-physical table cache

Abstract:

A method for managing sequential-write-based partitions in a logical-to-physical table cache is described. The method includes locating, by a memory subsystem, a first entry in a first sequential write partition in the cache that maps a first logical address in the set of sequential logical addresses of a read request to a first physical address, wherein each entry in the first sequential write partition corresponds to two sequential logical addresses that were sequentially written to sequential physical addresses of memory components of the memory subsystem. The method further includes determining, based on the first entry, the first physical address associated with the first logical address and a second physical address associated with a second logical address in the set of sequential logical addresses and fulfilling, by the memory subsystem, the read request based at least on the first physical address and the second physical address.
