摘要: A flash storage device comprises a plurality of data blocks, each data block comprising a plurality of data segments, a system memory, and a controller. The controller is configured to cache in the system memory a plurality of data sectors to be written, to write to a first one of the plurality of data segments a first one of the plurality of data sectors, to write to the first one of the plurality of data segments a first portion of a second one of the plurality of data sectors, and to write to a second one of the plurality of data segments a second portion of the second one of the plurality of data sectors.

摘要: Methods and systems for the prioritized erasure of data blocks in a flash storage device are provided. A data block in the flash storage device is selected for erasure based upon the number of valid data segments therein, thereby minimizing the number of data segments that are carried over to another data block before erasing the selected data block. The overhead of write operations in the flash storage device is therefore greatly reduced, and the overall performance thereof greatly increased. A method for managing memory operations in a flash storage device having a plurality of data blocks comprises the steps of selecting one of the plurality of data blocks for erasure based upon a number of valid data segments therein, and erasing the selected one of the plurality of data blocks.
