Management of memory array with magnetic random access memory (MRAM)

摘要

An embodiment of the invention includes a mass storage device with a storage media that includes magnetic random access memory (MRAM) devices with a NAND flash interface and NAND flash memory devices that are coupled to the MRAM devices. The storage media is partitioned into a hybrid reserved area made of a combination of MRAM array NAND array and hybrid user area made of a combination of MRAM array and NAND array and further includes a controller with a host interface and flash interface coupled to the MRAM and NAND flash memory devices through a flash interface.
