Abstract:
Apparatus and method for data integrity management in a data storage device. In accordance with some embodiments, a controller transfers user data blocks between a host device and a main memory. Each user data block has an associated logical address. A data integrity manager generates and stores a verification code for each user data block in a table structure in a local memory. The data integrity manager uses the verification code to independently verify a most current version of a selected user data block is being retrieved by the controller from the main memory during a host read request.
