Embodiment Construction

[0051] Such as figure 2 As shown, an embodiment of the present invention utilizes MRAM as a storage system for editing buffer areas. The storage system is used in mobile devices, such as mobile phones, including MRAM and NAND chips. MRAM includes editing buffer areas for caching file editing content. NAND chips are used to store file data.

[0052] The MRAM is connected to the main control chip of the mobile phone through the DDR DRAM interface.

[0053] For mobile phones, block storage devices are NAND chips, eMMC, SD cards, and microSD cards.

[0054] Use a part of the MRAM space as a cache for file editing. When the user saves a file, only the editing buffer in the MRAM is updated, and the NAND flash memory is not erased, thus prolonging the service life of the system and reducing the storage load of the system.

[0055] Such as image 3 As shown, another embodiment of the present invention utilizes MRAM as a storage system for editing buffer areas. The storage system i...

Abstract

The present invention provides a storage system using an MRAM as an editing buffer. The storage system comprises an MRAM and a block storage device. The MRAM comprises an editing buffer, which is used for buffering file editing content; and the block storage device is used for storing file data. The present invention further provides an editing buffer method for the storage system using the MRAM as the editing buffer. The MRAM is used as the editing buffer, and when a user saves a file, only the editing buffer in the MRAM is updated without erasing and writing an NAND flash memory, so that the service life of the system can be prolonged, and the storage load of the system is reduced.

Description

technical field [0001] The invention relates to a storage system, in particular to a storage system using MRAM as an edit buffer area and an edit buffer method. Background technique [0002] Now in computers, smartphones, and tablet computers, user data and files are stored in hard disks, or in NAND flash memory chips and solid-state hard disks composed of NAND flash memory. The replacement of traditional mechanical hard drives by NAND and solid-state drives is another major trend in industrial development. [0003] The NAND flash memory in the hard disk and solid-state disk is a block device that can be read and written as a whole. The smallest unit that can be read is called a page, and the smallest unit that can be erased is called a block. A block is often composed of It consists of many pages, and the pages inside can be individually written after the block is erased. [0004] One problem with NAND flash memory is that NAND has a finite lifetime. After each page in i...
