CONTROLLER PROVIDING SINGLE VIRTUALIZED ECC ALGORITHM, STORAGE SYSTEM INCLUDING THIS CONTROLLER, AND METHOD OF MANAGING THIS STORAGE SYSTEM

摘要

PROBLEM TO BE SOLVED: To allow a single virtualized ECC-NAND controller to service multiple NAND memory structures.SOLUTION: A single virtualized ECC-NAND controller 26 executes an ECC algorithm and manages a stack 24 of NAND flash memories. The virtualized ECC NAND controller 26 allows a host processor 20 to drive the stack of flash memory devices as a single NAND chip while the controller 26 redirects data to a selected NAND memory device in the stack 24.
