Abstract
According to one embodiment, a latch-type sense amplifier can reduce noise at a signal input that may be generated by capacitive coupling of a sense amplifier latch enable signal. A latch-type sense amplifier may include a first transfer gate TG between a first input SA and a first latch node N and a second transfer gate TG between a second input SA and a second latch node N A first transfer gate may include complementary transistors NM and PM Transistor NM can receive a control signal /SE at a control gate while transistor PM can receive a complementary control signal SE at a control gate. Transistor NM may include a parasitic capacitance CON and transistor PM may include a parasitic capacitance COP that is essentially equivalent to CON. In such an arrangement, noise at first input SA generated by capacitive coupling of a control signal SE can be reduced and/or cancelled by noise generated by capacitive coupling of a complementary control signal /SE.
