  • Patent number: 5815430
    Abstract: A circuit and method for reducing compensation of a ferroelectric capacitor in a cell of a memory array allows the capacitor's hysteresis loop to be repositioned toward its uncompensated position by pulsing the electrodes of the memory cell capacitors, via the memory array plate line, one or more additional times whenever a "write" occurs to the memory array. As a result, the ferroelectric capacitor delivers a signal of greater strength to the memory device sense amps upon a subsequent "read" operation significantly enhancing overall reliability and yield yet without reducing overall device endurance.
