Method and device for managing general flash memory storage array

Abstract

The invention provides a method and device for managing a general flash memory storage array and the method comprises the steps: determining an array address pointer of a block of a UFS storage array,building an FIFO, and enabling the table entry of the FIFO to correspond to the array address pointer; when an externally input command to be executed is a write-in command, executing the write-in command; determining a target table entry of the to-be-executed file according to the size of the to-be-executed file and the current table entry pointed by the pointer register, then storing the to-be-executed file in the corresponding target block in parallel according to the corresponding target array address pointer, and storing the file identifier and each target table entry; taking a table item pointed by the pointer register after sequentially moving each target table item from the current table item as the current table item; when the externally input to-be-executed command is not the write-in command, determining each corresponding specified table item according to the specified file identifier of the specified file corresponding to the to-be-executed command, then determining the corresponding specified array address pointer, and then executing the operation corresponding to the to-be-executed command on the information in the corresponding specified block.

Description

technical field [0001] The invention relates to the technical field of IC design, in particular to a management method and device for a general-purpose flash memory storage array. Background technique [0002] As a non-volatile memory, Universal Flash Storage (UFS) can bring higher reading and writing speeds and more reliable stability to smart terminals. It has been widely used in smart terminals and is gradually replacing embedded The status of the multimedia memory card (embedded Multi Media Card, eMMC). [0003] At present, most UFS chips are single-chip applications, which basically meet the needs in embedded fields such as mobile phones. However, in some occasions that have high requirements for speed and capacity, a single UFS chip cannot meet the high requirements of users, resulting in poor user experience. Contents of the invention [0004] Embodiments of the present invention provide a management method and device for a general-purpose flash memory storage arr...
