ABSTRACT:
A device for error correction includes a memory control module to disable error processing for a memory location depending on the state of a status indicator. The status indicator can be set so that error processing is disabled when valid error correction and detection information for the memory location is not available, such as after a reset or power-on event. In addition, the memory control module can promote partial write requests to full write requests when error processing is disabled to ensure that valid error detection and correction data is calculated for the memory location. By disabling error processing until valid error detection and correction information is available, the number of unnecessary or invalid error processing operations is reduced, thereby conserving device resources.
