    摘要: A six transistor SRAM cell for single-ended sensing is described along with related memory architecture. The cell comprises a bistable circuit connected to complementary bit lines through a pair of passgate transistors. One of the passgate transistors has a lower threshold voltage than the other transistor. The lower threshold voltage is used to couple the cell to a single-ended sense amplifier through one of the bit lines. In one embodiment fewer than all the bit lines in an array are precharged in order to reduce power consumption in the array.

    摘要: In one embodiment of the invention, a semiconductor circuit includes a first group of field effect transistors that are forward body biased and have threshold voltages and a second group of field effect transistors that are not forward body biased and have threshold voltages that are higher than the threshold voltages of the first group of field transistors. In another embodiment of the invention, a semiconductor circuit includes first and second groups of field effect transistors. The circuit includes voltage source circuitry to provide voltage signals to bodies of the first group of field effect transistors to forward body bias the transistors of the first group. When the voltage signals are applied, the transistors of the first group have lower threshold voltages than do the transistors of the second group, except that there may be unintentional variations in threshold voltages due to parameter variations. Other aspects of the invention include forward biased decoupling transistors and a method of testing for leakage.

    摘要: A capacitor includes a substrate (110, 210), a first electrically insulating layer (120, 220) over the substrate, and a fin (130, 231) including a semiconducting material (135) over the first electrically insulating layer. A first electrically conducting layer (140, 810) is located over the first electrically insulating layer and adjacent to the fin. A second electrically insulating layer (150, 910) is located adjacent to the first electrically conducting layer, and a second electrically conducting layer (160, 1010) is located adjacent to the second electrically insulating layer. The first and second electrically conducting layers together with the second electrically insulating layer form a metal-insulator-metal stack that greatly increases the capacitance area of the capacitor. In one embodiment the capacitor is formed using what may be referred to as a removable metal gate (RMG) approach.
