  • Differential sense amplifier circuit and method triggered by a clock signal through a switch circuit
    Patent number: 7323911
    Abstract: A differential sense amplifier is described that can be configured as a preamplifier or a latch circuit as triggered by a clock signal connected to a switch circuit. When the clock signal is set at a first signal level, the switch circuit in the differential sense amplifier is activated so that the differential sense amplifier is configured as a preamplifier with a positive feedback circuit. When the clock signal is set at a second signal level, the switch circuit in the differential sense amplifier is deactivated so that the differential sense amplifier is configured as the latch circuit. For one read cycle, the differential sense amplifier operates first as the preamplifier and then as the latch circuit.
