Abstract
A data storage device includes a memory device and a controller coupled to the memory device. The controller comprises an XOR module, an ECC module, a scrambler, an encoder, and comparison logic. The controller is configured to retrieve data from the memory device, decode the retrieved data, execute XOR protection logic on the decoded data, encode the decoded data, and compare the encoded data to the retrieved data stored in the memory device.
