DATA MANAGEMENT WITH MODULAR ERASE IN A DATA STORAGE SYSTEM

摘要

A system and method of data management with modular erase in a data storage system with a memory array having an erase block and a target block with the target block in a logical unit separate from the erase block including: performing an erase operation on the erase block, the erase operation having an operation matrix configured for partial erasing of the erase block; updating a command status for the erase block; enabling an intervening command on the target block based on the command status indicating an incomplete erase status with the intervening command updating the command status; performing an erase optimization based on the command status; performing an additional erase operation based on the erase optimization; and updating the command status to an erase complete status based on the additional erase operation.

1. A method of data management with modular erase in a data storage system with a memory array having an erase block and a target block with the target block in a logical unit separate from the erase block, comprising:
performing an erase operation on the erase block, the erase operation having an operation matrix configured for partial erasing of the erase block; updating a command status for the erase block; enabling an intervening command on the target block based on the command status indicating an incomplete erase status with the intervening command updating the command status; performing an erase optimization based on the command status; performing an additional erase operation based on the erase optimization; and updating the command status to an erase complete status based on the additional erase operation.
