    摘要: An integrated circuit, such as a memory macro, includes multiple power rails supporting first and second voltage differentials, with the second voltage differential being smaller than the first voltage differential. Signal lines in the integrated circuit are driven with the small voltage swing, which is generated by small swing circuits. The integrated circuit further includes regeneration circuits, which are receiving small voltage swing inputs and are outputting first, or full voltage swings. The application of the small voltage swing to the signal lines saves power in the integrated circuit. A wide bandwidth, full-wordline I/O, memory integrated circuit has simultaneously operable connection paths between essentially all the memory cells that are attached to the same wordline and the corresponding I/O terminals, and it has a single ended data-line structure.

    摘要: A new type of static RAM cell is disclosed that is based on a gated diode and its voltage amplification characteristic. The cell combines the advantages of a static RAM, in which data refresh is not needed, and those of gated diode cells, which are scalable to low voltages, have high signal to noise ratio, high signal margin, and tolerance to process variations, to form a single high performance static memory cell. This new cell has independent read and write paths, which allow for separate optimization of the read (R) and write (W) events, and enable dual-port R/W operation. Furthermore, storage node disturbance during the read and write operations are eliminated, which greatly improves cell stability and scalability for future technologies.

    摘要: A circuit comprises a control line and a two terminal semiconductor device having first and second terminals. The first terminal is coupled to a signal line, and the second terminal is coupled to the control line. The two terminal semiconductor device is adapted to have a capacitance when a voltage on the first terminal relative to the second terminal is above a threshold voltage and to have a smaller capacitance when a voltage on the first terminal relative to the second terminal is below the threshold voltage. The control line is coupled to a control signal and the signal line is coupled to a signal and is output of the circuit. A signal is placed on the signal line and voltage on the control line is modified (e.g., raised in the case of n-type devices, or lowered for a p-type devices). When the signal falls below the threshold voltage, the two terminal semiconductor device acts as a very small capacitor and the output of the circuit will be a small value. When the signal is above the threshold voltage, the two terminal semiconductor device acts as a large capacitor and the output of the circuit will be influenced by both the value of the signal and the value of the modified voltage on the control line and therefore the signal will be amplified.
