Abstract:
An FRAM device can comprise a sense amplifier and at least a first bitcell. The first bitcell can have a bit line and a complimentary bit line that connects to the sense amplifier. A first precharge circuit responds to a first control signal during a test mode of operation to precharge the bit line with respect to a first voltage while a second precharge circuit responds to a second control signal (that is different from the first control signal) during the test mode of operation to precharge the complimentary bit line with respect to a test voltage that is different than the first voltage (such as, but not limited to, a test voltage of choice such as a voltage that is greater than ground but less than the first voltage).
