Abstract
The present disclosure relates to a structure which includes a twin-cell memory which is configured to program a plurality of write operations, a current sense amplifier which is connected to the twin-cell memory and is configured to sense a current differential and latch a differential voltage based on the current differential, and at least one current source which is connected to the current sense amplifier and is configured to add an offset current to the current sense amplifier to create the differential voltage.
