Patent ID: 7242629

Claim:
A latch circuit comprising: a pass device comprising a control terminal and first and second terminals, the first terminal of the pass device coupled to a signal line, the control terminal of the pass device coupled to a first clock line; a precharge device comprising a control terminal and first and second terminal, the control terminal of the precharge device coupled to a second clock line, the first terminal of the precharge device coupled to a power supply voltage, and the second terminal of the precharge device coupled to the first terminal of the pass device; a gated diode comprising first and second terminals, the first terminal of the gated diode coupled to the second terminal of the pass device, and the second terminal of the gated diode coupled to a third clock line; and an output device comprising an input and an output, the input of output device coupled to the first terminal of the gated diode and to the second terminal of the pass device, the output of the output device adapted to be the output of the latch circuit, the output device adapted to produce an output signal on the output of a sense amplifier circuit based on a voltage on the first terminal of the gated diode; wherein the signal line is adapted to be coupled to an input signal.
