摘要： A sense amplifier transition encodes an output signal onto a bus such that the bus signal only transitions when a sensed bit line has a state different from the state of a previously sensed bit line. The sense amplifier includes a storage element that changes state when the bus signal is asserted. The output of the sense amplifier is conditionally inverted based on the state of the storage element.

摘要： An apparatus includes: a signal receiving unit receiving an input signal and presenting a first signal varying within a first signal range; a signal treating unit coupled with the signal receiving unit, receiving the first signal and presenting a second signal varying within a second signal range; and an output unit coupled with the signal treating unit. The signal treating unit and the output unit receive a control signal. The signal treating unit responds to the control signal to provide the second signal to the output unit when the control signal has a first value and to not provide the second signal to the output unit when the control signal has a second value. The output unit permits presentation of an output signal when the control signal has the first value and establishes the output signal at a predetermined value when the control signal has the second value.

摘要： A dual-supply voltage latch includes a data input node to receive an input data, internal nodes to hold the input data, and an output node to output an output data. The latch also includes clock input nodes to receive a clock signal. The data input, internal, and data output nodes are at a higher potential than the clock nodes. Since clock nodes are high activity nodes, less potential on these nodes reduces the energy consumed by the latch. Although the data nodes and clock nodes are at different potentials, the latch has reduced static power dissipation.

摘要： A logic circuit performs an internal level conversion function by driving portions of the circuit with different supply voltages. In one embodiment, first and second stage storage circuits are driven with different supply voltages. In another embodiment, first and second stage storage circuits are driven with a first supply voltage and an inverter coupled to the first stage storage circuit is driven with a second supply voltage. In either case, data transfer into the storage circuits may be controlled by different states of a clock signal. The logic circuit may be a flip-flop circuit, a latch circuit, or another type of circuit.
