    摘要: A novel methodology for the construction and operation of logical circuits and gates that make use of and contact to a fourth terminal (substrates/bodies) of MOSFET devices is described in detail. The novel construction and operation provides for maintaining such body-contacted MOSFET devices at a lower threshold voltage (VTh) when actively on (to increase overdrive and performance), and at a higher relative threshold voltage when off (to reduce leakage power). Because the threshold potential of a gate moves inversely to its body potential, it follows then that in general, the body of a given device must be tied to the inverse of the device's drain voltage to achieve such a desirable threshold potential modulation effect for improved device, circuit, gate and logical family operation.

    摘要: A multi-port register file (e.g., memory element) is provided in which each read port of the register file is located in a separate wafer above and/or below the primary data storage element. This is achieved in the present invention by utilizing three-dimensional integration in which multiple active circuit layers are vertically stacked and vertically aligned interconnects are employed to connect a device from one of the stacked layers to another device in another stacked layer.

    摘要: A system, method and program product for determining a history state of data in a data retaining device are disclosed. A state of a partially-depleted silicon-on-insulator (PD SOI) device coupled to a data retaining device is measured to indicate a body voltage of the PD SOI device. The body voltage of the PD SOI device may indicate, among others, how long the PD SOI device has been idling, which indirectly indicates how long data in the data retaining device has not been accessed. As such, the current invention may be used efficiently with, e.g., a cache replacement algorithm in a management of the data retaining device.

    摘要: A computer system for designing a low leakage monotonic CMOS logic circuit. The system performing the computer implements steps of: (a) specifying a reference PFET having its threshold voltage and its gate dielectric thickness and a reference NFET having its threshold voltage and its gate dielectric thickness; (b) synthesizing a schematic circuit design with standard design elements, the standard design elements including one or more reference PFETS and one or more reference NFETs; (c) analyzing one or more circuits for logic stages having predominantly high input logic states or predominantly low input logic states; (d) selecting one or more logic stages determined to have predominantly high input logic states or predominantly low input logic states; and (e) replacing the standard design elements of the selected logic stages with reduced current leakage elements.
