Abstract
Many error correction schemes fail to correct for double-bit errors and a module must be replaced when these double-bit errors occur repeatedly at the same address. This helps prevent data corruption. In an embodiment, the addresses for one of the memory devices exhibiting a single-bit error (but not the other also exhibiting a single bit error) is transformed before the internal memory arrays are accessed. This has the effect of moving one of the error prone memory cells to a different external (to the module) address such that there is only one error prone bit that is accessed by the previously double-bit error prone address. Thus, a double-bit error at the original address is remapped into two correctable single-bit errors that are at different addresses.
