Abstract
Systems, apparatus and methods for generation of XOR signature metadata and XOR signature management are presented. In one or more embodiments, a storage device controller includes a host interface, configured to receive one or more string lines (SLs) of data from a host, the one or more SLs to be programmed into a non-volatile memory (NVM), and processing circuitry. The processing circuitry is configured to, for each of the one or more SLs, generate signature metadata and provide the signature metadata in a header of the SL. The processing circuitry is still further configured to XOR two or more of the SLs with their respective signature metadata to generate a snapshot, and write the snapshot to the NVM.
