Abstract:
1. A mass storage device coupled to a host and comprising a storage media comprising a plurality of magnetic random access memory (MRAM) devices, including MRAM memory and having a NAND flash interface circuit, the storage media further comprising a plurality of NAND flash memory devices, including NAND flash memory, the storage device partitioned into a plurality of Logical Units (LUNs) based on the capabilities and resources of the mass storage device, the LUNs being made of a combination of MRAM and NAND flash memory of the MRAM and NAND flash memory devices, each LUN being mapped to a particular type of media or collection of different types of media in accordance with its utilization; a controller with NAND flash interface coupled to the MRAM and NAND flash memory devices through a flash interface, the controller with NAND flash device being coupled to the host through a host interface, wherein the host utilizes the plurality of LUNs based on the LUNs' attributes to optimize its performance.
