Abstract: The disclosed architecture uses address mapping to map a block address on a host interface to an internal block address of a non-volatile memory (NVM) device. The block address is mapped to an internal chip select for selecting a Concurrently Addressable Unit (CAU) identified by the block address. The disclosed architecture supports generic NVM commands for read, write, erase and get status operations. The architecture also supports an extended command set for supporting read and write operations that leverage a multiple CAU architecture.
