Abstract

Error correction codes (ECCs) for memories are generally designed for 2-bit error detection and 1-bit correction. If applied to 3-bit errors, they would lead to a 1-bit error indication, with the 1-bit correction carried out in response to damaging user data. To avoid this, an ECC controller is proposed.
