Patent ID: 10409500

Abstract:
One embodiment provides a memory controller. The memory controller includes logical block address (LBA) section defining logic to define a plurality of LBA sections for a memory device circuitry, each section including a range of LBAs, and each section including a unique indirection-unit (IU) granularity; wherein the IU granularity defines a physical region size of the memory device. The LBA section defining logic also to generate a plurality of logical-to-physical (L2P) tables to map a plurality of LBAs to physical locations of the memory device, each L2P table corresponding to an LBA section. The memory controller also includes LBA section notification logic to notify a file system of the plurality of LBA sections to enable the file system to issue a read and/or write command having an LBA based on an IU granularity associated with an LBA section.
