Abstract
One embodiment provides a silent data corruption (SDC) mitigation circuitry. The SDC mitigation circuitry includes a comparator circuitry and an SDC mitigation logic. The comparator circuitry is to compare a successful decoded codeword and a corresponding received codeword, the successful decoded codeword having been deemed a success by an error correction circuitry. The SDC mitigation logic is to reject the successful decoded codeword if a distance between the corresponding received codeword and the successful decoded codeword is greater than or equal to a threshold.
Claims21
A silent data corruption (SDC) mitigation circuitry comprising:
- a comparator circuitry to compare a successful decoded codeword and a corresponding received codeword, the successful decoded codeword having been deemed a success by an error correction circuitry;
- and
- an SDC mitigation logic to reject the successful decoded codeword if a distance between the corresponding received codeword and the successful decoded codeword is greater than or equal to a threshold.
A method comprising:
- comparing, by a comparator circuitry, a successful decoded codeword and a corresponding received codeword, the successful decoded codeword having been deemed a success by an error correction circuitry;
- and
- rejecting, by an SDC mitigation logic, the successful decoded codeword if a distance between the corresponding received codeword and the successful decoded codeword is greater than or equal to a threshold.
A system comprising:
- a processor circuitry;
- a memory device;
- and
- a memory controller comprising a silent data corruption (SDC) mitigation circuitry, the SDC mitigation circuitry comprising:
- a comparator circuitry to compare a successful decoded codeword and a corresponding received codeword, the successful decoded codeword having been deemed a success by an error correction circuitry;
- and
- an SDC mitigation logic to reject the successful decoded codeword if a distance between the corresponding received codeword and the successful decoded codeword is greater than or equal to a threshold.
