    Abstract: The present invention discloses a differential logic circuit and sensing method providing differential sensing with greater speed and higher density than prior art techniques. One or more input signals are provided to a logic array and two output signals are produced from the logic array wherein one output signal of the logic array is a bit-line and one output signal of the logic array is a bit-bar-line as a reference signal, wherein both signals are provided as input signals to a differential sense amplifier having a binary output signal. The bit-line and the bit-bar-line are precharged to the same voltage level and a controlled input source-grounded transistor having less than fill drive strength is coupled to the bit-bar-line. A source-grounded transistor is coupled to each input signal of the logic array and is programmable to the bit-line by coupling the drain of the source-grounded transistor to the bit-line. A corresponding sourceless transistor, having a gate and a drain, but no source, is coupled to each input signal of the logic array and is programmable to the bit-bar-line by coupling the drain of the sourceless transistor to the bit-bar-line. The source-grounded transistors and the corresponding sourceless transistors are programmed identically providing substantially the same capacitance load on the bit-line and the bit-bar-line.

    Abstract: Control circuitry for a register file is provided which allows immediate or rapid output of input write data by bypassing the need to store the data and then read it out of the register file. In each pairing of memory cells, the read line is coupled to both the storage cell and to the write line. The connection to the write line is configured so that, when the connection is activated, such as by turning on a transistor, the magnitude of the data signal provided from the write line to the read line is large enough to overpower whatever signal is being output to the read line from the memory cell. In this way, when the connection from the write line to the read line is activated, the write line will output the information on the read line, rather than the information in the storage cell. The information on the read line can then be output onto the write line without the information first being stored in the memory cell. This is advantageous when the write data is available at a time when its validity is unknown. Preferably, the device is further configured to permit writing of the data from the write line into the memory cell once the validity of the data is ascertained, e.g., under control of a word line.

    Abstract: A transistor structure is provided comprising a source region having a N+ source region and a N− lightly doped source region. The structure also comprises a drain region having a N+ drain region and a N− lightly doped drain region. A P++ heavily doped region is provided. The P++ region resides alongside at least a portion of at least one of the N− lightly doped source region and N− lightly doped drain region. A P+ body region resides below a gate of the device and between the source and drain regions. The P+⇄ heavily doped region provides a capacitive coupling between a body region and the gate of the device and form a capacitive voltage divider with the junction capacitance of the device.

    Abstract: A coupling capacitor is coupled between the gate and the body region of a MOSFET (Metal Oxide Semiconductor Field Effect Transistor). The body region of the MOSFET is electrically isolated to form a floating body region. The capacitance of the coupling capacitor is designed such that a BJT (Bipolar Junction Transistor) connected in parallel with the MOSFET turns on when the MOSFET turns on. In addition such a design of the coupling capacitor lowers the magnitude of the threshold voltage of the MOSFET when the MOSFET is turned on. Furthermore, the capacitance of the coupling capacitor is designed such that the magnitude of the threshold voltage of the MOSFET is raised when the MOSFET is turned off. Thus, the MOSFET type device of the present invention has both higher drive current when the MOSFET is turned on and lower steady state power dissipation when the MOSFET is turned off with a variable threshold voltage.

    Abstract: A method of forming field isolation in a semiconductor substrate, such as shallow oxide trenches, for isolation of FET transistors, including complementary FETs such as CMOS, with selected sections of said trenches extending above the substrate and being coplanar with the upper surface of subsequently formed polysilicon gates. An etch protective layer is used during the formation and the filling of the trench openings so that the top of the trenches are coplanar with upper surface of the etch protective layer. Selected sections of the trenches are masked and protected prior to planarization of the non-masked trenches to the bottom edge of the etch protective layer. After deposition and planarization of the poly, the upper surface of a deposited polysilicon layer for forming polysilicon gates of FET transistors is coplanar and self-aligned with the upwardly extending selected sections of the field isolation trenches.
