Abstract: In some embodiments, detecting resistance in a resistive memory cell may be done using a pulse edge. For example, a pulse may be applied through a resistive memory data cell and another through a reference delay circuit to determine which path has the larger delay in order to determine the resistive state of the data cell in question.

Abstract: An approach for power reduction of an integrated circuit device. In response to detecting a change in an activity factor associated with an integrated circuit device from a first activity factor to a second activity factor, a supply voltage and a body bias associated with the integrated circuit device are adjusted based on the second activity factor to reduce power consumption. For one aspect, the supply voltage and body bias are adjusted to maintain a substantially constant operating frequency for the integrated circuit device.

Abstract: A method and apparatus for a four transistor SRAM comprising an array or block of cells. Each cell comprises a pair of pass transistors and a pair of pull-down transistors. In one embodiment of the invention, when the SRAM block is in a standby mode, the difference between the voltage at the gate and the voltage at the source of each pass transistor is greater than 0, and less than the threshold voltage of the pass transistor. In one embodiment of the invention a ground connection of the memory cell is switched such that when the SRAM block is in the standby mode, the ground connection is a virtual ground connection and when the SRAM block is in an active mode the ground connection is a global ground connection.

Abstract: A device to sense changes in current level almost instantaneously and convert those current levels, almost instantaneously, into voltage levels that may be used by a microprocessor for logical and mathematical operations. This device employs a current conveyer to receive two inputs representing current levels. Once a sufficient difference in current levels is detected by the current conveyer, the current from each input is passed to a P-sense amplifier that converts the current to an equivalent voltage level and amplifies that voltage level.
