Abstract
In a system where a memory device performs on-die ECC, the ECC operates on N-bit data words as two (N/2)-bit segments, with a code matrix having a corresponding N codes that can be operated on as a first portion of (N/2) codes and a second portion of (N/2) codes to compute first and second error checks for first and second (N/2)-bit segments of the data word, respectively. In the code matrix, a bitwise XOR of any two codes in the first portion of the code matrix or any two codes in the second portion of the code matrix results in a code that is either not in the code matrix or is in the other portion of the code matrix. Thus, a miscorrected double bit error in one portion causes a bit to be toggled in the other portion instead of creating a triple bit error.
