A memory and storage device includes a data management system for transferring data units referenced by logical addresses. The data management system maps the logical addresses to sequential virtual addresses according to the order the data units are received. The data management system also maps the sequential virtual addresses to sequential physical addresses in a memory block of a memory device. Additionally, the data management system can modify a data unit in the memory block by copying any other valid data units in the memory block to another memory block and writing the modified data unit into this other memory block. The data management system writes the valid data units and the modified data unit into sequential physical addresses of this other memory block.

System and method for accessing interleaved data in a memory device

A data storage system using flash storage maintains a status indicator corresponding to data written into the flash storage. The status indictor of the data indicates whether a disruption, such as a power disruption or a device disconnection, occurred when the data was being written into the flash storage. The data storage system determines whether the data may be corrupted based on one or more of the status indictors. The data storage system may make this determination at a selected time or after a power-up of the data storage system. If the data is determined to possibly be corrupted, the data storage system may optionally discard the corrupted data from the flash storage or flag the corrupted data for future removal.

System and method for detecting and reducing data corruption in a storage device

A data management for a flash memory device is disclosed. The device includes a screen virtual sector table and a virtual unit versus physical unit table (V2P table) for each block. With the auxiliary of the screen virtual sector table and v2p table, the data programming into the target block of the flash memory is in accordance with the data receiving order, which is from lower page number to higher page number in case the target block is free. The data can be written into the target block contains data already through one or two temporal block(s). The conventional LBA data transfer protocol can still be applied to the flash memory device of this invention.
