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