摘要： An approach for performing data block location verification includes inserting an address value into a data block that identifies a desired location in nonvolatile memory for storing the data block. Prior to performing an operation that stores the data block to the nonvolatile memory, a determination is made whether the address value in the data block correctly identifies the location in nonvolatile memory into which the operation will store the data block. The operation is performed only if the address value in the data block correctly identifies the location in nonvolatile memory into which the operation will store the data block. After the data block is read from the nonvolatile memory, an additional determination may be made to determine whether the data block was read from the desired location in the nonvolatile memory.

摘要： A method and apparatus is provided for maintaining data integrity. According to the method, a physical checksum calculation is performed on a block of data. After performing the physical checksum calculation, a logical check is performed on the data contained with the block of data. If the block of data passes the logical check, then the block of data may be written to nonvolatile memory. Thereafter, when the block of data is read from nonvolatile memory a physical checksum verification procedure is performed on the block of data to determine whether the block of data was corrupted after performing the logical check on the data contained with the block of data.
