Abstract

A request that specifies a logical address associated with a host-initiated operation directed at a first portion of a memory device is received. A logical to physical (L2P) table is accessed. The L2P table comprises a mapping between logical addresses and physical addresses in a second portion of the memory device. An entry in the L2P table that corresponds to the logical address is identified and is determined to point to an entry in a read cache table. Based on an entry number of the entry in the read cache table, a chunk address of a chunk from among multiple chunks of a read cache is calculated. A physical address that corresponds to the logical address specified by the request is identified by accessing the chunk of read cache. The host-initiated operation is performed at a physical location within the first portion of the memory device corresponding the physical address.
