Data loss protection for memory systems and devices

Data loss protection for memory systems and devices

Systems, methods, and devices prevent data loss in memory devices. Systems may include a non-volatile memory device that includes a first data unit configured to store data for the non-volatile memory device and associated metadata, and a second data unit configured to store data for the non-volatil...

description Systems, methods, and devices prevent data loss in memory devices. Systems may include a non-volatile memory device that includes a first data unit configured to store data for the non-volatile memory device and associated metadata, and a second data unit configured to store data for the non-volatile memory device and associated metadata, wherein the first data unit and second data unit are configured to alternate storing a most recent version of the data and associated metadata. The systems may also include control circuitry configured to read metadata from the first data unit and the second data unit, identify the first data unit as an inactive data unit based on contents of the first data unit and the second data unit, and perform one or more update operations such that the first data unit is updated and set as an active unit when the update operations are complete.
