    摘要: Some embodiments provide pre-charge of a bit-line coupled to a memory cell to a reference voltage using a pre-charge device, discharge of the bit-line based on a value stored by the memory cell, injection during the discharge, of a first current into the bit-line using the pre-charge device, and injection, during the discharge, of a second current into a reference bit-line using a second pre-charge device. Also during the discharge, a difference is sensed between a voltage on the bit-line and a voltage on the reference bit-line.

    摘要: A circuit includes a first driver, a second driver, and a transformer coupled to the first and second driver. In operation, the first driver receives a first signal from a first input port, the second driver receives a time-delayed version of the first signal from a second input port, and the transformer provides provide an output signal to an output port. A method includes receiving a first input signal, receiving a second input signal, and then processing the first input signal and the second input signal. The second input signal is a time-delayed version of the first input signal and the processing of the first input signal and the second input signal generates a half-raised cosine signal.

    摘要: A domino logic circuit includes a clocked precharge stage coupled to a positive voltage rail with the precharge stage having an input. An evaluation network adapted to receive at least one input is coupled between the precharge stage and a common voltage rail. A static CMOS stage is coupled to the positive voltage rail, and includes an input and an output, the input being coupled to a junction formed by the precharge stage and the evaluation network. A negative voltage rail is coupled to the static CMOS stage to precharge the output negative.

    摘要: Disclosed herein are semiconductor device arrays, such as, Field Programmable Gate Arrays (FPGAs) and Complex Programmable Logic Arrays (CPLAs) that use high-density Spin Transfer Torque (STT)-based memory elements. STT-based memory elements can either be stand-alone FPGAs/CPLAs, or can be embedded in microprocessors and/or digital signal processing (DSP) system-on-chip (SoC) to provide design flexibility for implementing low power, scalable, secure and reconfigurable hardware architecture. Because the configuration is stored on the FPGA/CPLA die itself, the need for loading the configuration from external storage every time is eliminated when the device is powered on. In addition to instant startup, eliminating configuration I/O traffic results in power savings and possible pin count reduction. Security is greatly improved by eliminating the need to store configuration data in an external memory.
