Abstract :
The sense margin available for sensing by the sense amplifier during the read access of 1T-1C FRAM cells affects the accuracy of the reading process. In this paper, a procedure for determining the sensing window of the 1T-1C FRAM cell will be discussed. Also, three proposed techniques for increasing the sense margin will be discussed.
