    Abstract: A power control circuit for an integrated circuit module includes at least one switch device coupled between a supply voltage and a node of the integrated circuit module; and a switch control module having a first terminal coupled to the switch device and a second terminal coupled to the node of the integrated circuit module for controlling the switch device to pass the supply voltage to the node with or without a substantial voltage drop depending on an operation mode of the integrated circuit module, the switch control module having at least one capacitor for selectively discharging the node, thereby creating the substantial voltage drop for the supply voltage across the switch device.

    Abstract: A digital memory element has a sense circuit latch to read the value stored in a bit cell. Before addressing a word line, the bit lines are precharged. During the read operation, a bit line is coupled to a supply voltage through a bit cell memory element that has different resistances at logic states “0” and “1.” A reference bit line is coupled to the supply voltage through a comparison resistance value, especially a resistance between high and low resistance of the memory element in the two logic states. Voltages on the bit line and reference bit line ramp toward a switching threshold at rates related to the resistance values. The first line to discharge to switching threshold voltage sets the sense circuit latch.
