Abstract:
An apparatus includes a master latch circuit including a first circuit and a second circuit, and a slave latch circuit including a third circuit and a fourth circuit. The first circuit and the second circuit may be coupled to a first shared circuit node, and the third circuit and the fourth circuit may be coupled to a second shared circuit node. The master latch circuit may be configured to store a value of an input signal in response to an assertion of a clock signal. The slave latch circuit may be configured to store an output value of the master latch circuit in response to a de-assertion of the clock signal. The master latch circuit may also be configured to de-couple the first shared circuit node from a ground reference node in response to the de-assertion of the clock signal.
