Some embodiments provide a memory cell that includes a body region, a source region and a drain region. The body region is doped with charge carriers of a first type, the source region is disposed in the body region and doped with charge carriers of a second type, and the drain region is disposed in the body region and doped with charge carriers of the second type. The body region and the source region form a first junction, the body region and the drain region form a second junction, and a conductivity of the first junction from the body region to the source region in a case that the first junction is unbiased is substantially less than a conductivity of the second junction from the body region to the drain region in a case that the second junction is unbiased.

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.

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.

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.

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.
