Abstract
A memory device comprises a memory array and error correction circuitry coupled to the memory array. The error correction circuitry is configured to identify, in a data word retrieved from the memory array, at least one bit position corresponding to a predetermined defect location in the memory array, and to generate a corrected data word by automatically inverting a logic value at the identified bit position. This automatic logic inversion approach is particularly well suited for use in correcting output data errors associated with via defects and weak bit defects in high-density ROM devices.
