ABSTRACT:
A nonvolatile memory having a plurality of individually erasable blocks is used to store sectors of a file. A method of overwriting the file includes the step of receiving a frame of data. The logical sector that the frame is to be written to is determined. The logical sector corresponds to a first sector located at a first offset in a first block of the nonvolatile memory. The first block also has an associated first logical block number. The frame of data is written to a second sector. The second sector is located at a second offset in a spare block. The first and second offsets are identical. The logical block number of the spare block is updated to be the same as the first logical block number.
