Circuits And Methods For Correcting Errors In Memory

Abstract:

An electronic system includes a processor circuit, a memory circuit, and an error correction circuit. The error correction circuit receives information read from the memory circuit. The error correction circuit detects if the information contains an error. The error correction circuit corrects the error in the information to generate corrected information and provides the corrected information and an error signal to the processor circuit. The processor circuit provides the corrected information and a write command to the memory circuit based on the error signal indicating the error. The memory circuit overwrites the information stored in the memory circuit with the corrected information in response to the write command.
