Abstract
A sense amplifier () includes first and second inverters (and). The first inverter has an input terminal () and an OUT_B output node and a first transistor (). The second inverter () has an input terminal () and an OUT output node and a second transistor (). The OUT_B output node of the first inverter is coupled to an input terminal of the second inverter, and the OUT node of the second inverter is coupled to an input terminal of the first inverter. The sense amplifier does not use a reference current; therefore, the sense amplifier does not need a reference current generator. The sense amplifier needs only one enable signal to reset a latch () of the sense amplifier. When coupled to a non-volatile memory element, voltages at the output nodes are indicative of a logic level of a bit stored in the non-volatile memory element.
