Abstract

The present invention is directed to a storage device including a storage media and a controller coupled thereto through a high speed interface. The storage media includes one or more byte-addressable persistent memory devices, one or more block-addressable persistent memory devices, a hybrid reserved area spanning at least a portion of the one or more byte-addressable persistent memory devices, and a hybrid user area spanning at least a portion of the one or more block-addressable persistent memory devices. The controller uses the hybrid reserved area to store private data. Each of the one or more byte-addressable persistent memory devices may include one or more magnetic random access memory (MRAM) arrays. Each of the one or more block-addressable persistent memory devices may include one or more NAND flash memory arrays. The high speed interface may be a universal flash storage (UFS) interface that operates in the full-duplex mode.
