    摘要: A nondestructive read, three device BICMOS gain cell for a DRAM memory having two FETs and one bipolar device. The gain cell has an improved access time (less latency), can operate for longer periods of time before a refresh operation is required, requires a smaller storage capacitance than a traditional DRAM cell, and can be produced commercially at lower costs than are presently available. In a preferred embodiment, the gain cell comprises an n channel metal oxide semiconductor field effect write transistor having its gate connected to a write word line WLw. Its drain is connected to a storage node Vs having a storage capacitance Cs associated therewith, and its source is connected to a write bit line BLw. An n channel metal oxide semiconductor field effect read transistor has its gate connected to the storage node Vs and its source connected to a read word line WLr. A PNP transistor has its base connected to the drain of the read transistor and its emitter connected to a read bit line BLr. A second embodiment is constructed with p channel FETs and an NPN transistor.

    摘要: A method and apparatus for using multi-level signals in a gain cell is shown. The method involves of first, storing a value of a multi-level signal in the gain cell. A stepping waveform is then applied to the gain cell and the gain cell outputs a conduction signal when the level of the stepping waveform corresponds to the value of the multilevel signal that is stored within the gain cell. Finally, the value of the multi-level signal is determined through the conduction signal and the corresponding level of the stepping waveform. The gain cell includes an input device, a storage device and a level comparator, which responds to the stepping waveform generated from a stepping signal generator and outputs the conduction signal for determining the value of the multi-level signal stored in the storage device.

    摘要: An electronic semiconductor module, either memory or logic, having a driver circuit which includes a multiplicity of driver transistors, together with circuitry for simultaneously applying a first positive bias to a first select number of driver transistors to activate them to an operational state, a second positive bias to a second select number of driver transistors to place them in readiness for activation, and a negative bias to the remaining driver transistors to place them in a fully inactive state thereby reducing noise in the driver circuit. The first positive bias is greater than the transistor threshold voltage, preferably greater than two volts, the second positive bias is less than the threshold voltage, preferably less than one volt, and the negative bias is in the order of minus 0.3 volt. A method of reducing noise in the electronic semiconductor module is also described and includes the applying of a positive bias to a first select number of the transistors to activate them while simultaneously applying a second positive bias to a second select number of the transistors to ready them for activation, and a negative voltage to the remaining transistors to place each in a inactive condition.

    摘要: A gain cell in a memory array having read and write bitlines and wordlines, wherein the gain cell comprises a write transistor, a storage node, a read transistor, and a diode is disclosed. The write transistor allows the value of the write bitline to be stored onto the storage node when activated by the write wordline. The read transistor, which allows the stored value to be read, is coupled to the storage node and to the read bitline via the diode. The diode prevents the conduction of the read transistor in the opposite direction, thus preventing read interference from other cells and reducing bitline capacitance.

    摘要: A programmable element that has a first diode having an electrode and a first insulator disposed between the substrate and said electrode of said first device, said first insulator having a first value of a given characteristic, and an FET having an electrode and a second insulator disposed between the substrate and said electrode of said second device, said second insulator having a second value of said given characteristic that is different from said first value. The electrodes of the diode and the FET are coupled to one another, and a source of programming energy is coupled to the diode to cause it to permanently decrease in resistivity when programmed. The programmed state of the diode is indicated by a current in the FET, which is read by a sense latch. Thus a small resistance change in the diode translates to a large signal gain/change in the latch. This allows the diode to be programmed at lower voltages.

    摘要: A differential receiver for sensing small input voltage swings by using a built in reference voltage obtained by a difference in threshold voltage between a differential pair of closely spaced transistors. The difference in threshold voltage can be produced by different values of ion implantation of the gates of the transistor pair with the same material, or by dosages using different materials. The difference in threshold voltage can also be obtained by using different transistor channel lengths. The threshold voltages can also be modulated by the control of the transistor substrate voltages using a voltage control substrate means.
