摘要: A method and circuitry are described that permit one to utilize a partially functional integrated circuit memory. memory array is segregated into separate blocks can each be isolated minimize the amount of rendered unusable by defect. Circuitry also provided program cells within at least three amounts charge thereby increase storage remaining blocks.
