ABSTRACT:
Sense amplifier circuitry (SC) includes a differential amplifier (A) having a reference input and a memory input. The output of a first sense amplifier (SA1) is coupled to the reference input of the differential amplifier (A) and to the input of a second sense amplifier (SA2). The output of the second sense amplifier (SA2) is coupled to the memory input of the differential amplifier (A) and to the input of the first sense amplifier (SA1). The first sense amplifier (SAR) and the second sense amplifier (SA2) include identical mirror transistor circuits (M1, M2, M3, M4).
