Abstract

Disclosed is the technique of dynamically computing the redundancy of the data to be stored in a programmable memory. By using this technique, the entire memory can be protected including recently modified data in the memory.

Dynamic Redundancy Computation Used to Protect Programmable Memories

      Disclosed is the technique of dynamically computing the
redundancy of the data to be stored in a programmable memory.  By
using this technique, the entire memory can be protected including
recently modified data in the memory.

      The redundancy that protects a programmable memory device can
be computed just prior to programming the device by the software or
hardware that performs the programming.  This allows the redundancy
to cover the entire device including data that has recently been
generated or modified.  It also ensures that all of the data stored
in the device is covered, is covered efficiently, and can easily be
validated.
