    摘要: A very thin semiconductor film is used for channels of semiconductor memory elements such that leak currents are reduced by the quantum-mechanical containment effect in the direction of film thickness. The amount of electrical charge accumulated in each charge accumulating region is used to change the conductance between a source region and a drain region of each read transistor structure. This conductance change is utilized for data storage. The thickness of the channel of the write transistor structure is preferably no more than 5 nm. According to one embodiment, the channel of the write transistor is formed by a semiconductor film deposited on a surface intersecting a principal plane of the substrate.

    摘要: A pass-transistor logic circuit configuration that can form a high-speed chip in a small area with short wire length. In a selector circuit PMOS and NMOS transistors with different gate signals but with the same drain outputs are arranged, respectively, so their diffusion layers are shared. The PMOS and NMOS are staggered so that their gates are almost in line. With this arrangement, wires connecting drains of the PMOS and NMOS and wires connecting sources of the PMOS and NMOS do not intersect each other, so they can be wired with only the first wiring layer. Further, gate input signals can be wired with only polysilicon wires without crossing each other. The pass-transistor logic circuit is made to pass through the signal buffers before or after it is connected to the selector. This can make a compact, fast circuit.

    摘要: In order to produce a logic circuit excellent in circuit characteristics which are area, delay time and power consumption by combining pass transistor logic circuits and CMOS logic circuits, a binary decision diagram is created from a Boolean function, and respective nodes of the diagram are mapped into 2-inut, 1-output, 1-control input pass transistor selectors to synthesize a pass transistor logic circuit. In the pass transistor logic circuit, a pass transistor selector operating as a NAND or NOR logic with any one of its two inputs excluding the control input being fixed to a logical constant “1” or “0” is replaced with a CMOS gate operating as a NAND or NOR logic logically equivalent to the pass tansistor selector if the value of a predetermined circuit characteristic obtained by the replacement is closer to an optimal value (if the resulting logic circuit is smaller in area, delay time or power consumption than the original pass transistor logic circuit).

    摘要: For the relation between the first and second pass-transistor circuits (PT1, PT2), the output signal of the preceding-stage is supplied to the gate of the succeeding-stage, and for the relation between the second and third pass-transistor circuits (PT2, PT3), the output signal of the preceding-stage is supplied to the source-drain path of the succeeding-stage. The first pass-transistor circuit (PT1) receives on its first input node (In1) and second input node (In2) the first input signal and the second input signal that are logically independent from each other. This logic circuit requires a smaller number of transistors and is capable of reducing the power consumption and delay and accomplishing an intricate logic function.

    摘要: The semiconductor integrated circuit enjoys a high performance and can be produced at a low production cost and within a short time. A cell has an internal circuit connection such that an output terminal is connected to a plurality of input terminals through source-drain paths of active devices connected in the tree form, and gate electrodes of the active devices are connected to other input terminals. Two such cells having the same internal circuit connection, the same disposition of the internal circuit devices and the same disposition of the input/output terminals are disposed on the same chip, and mutually different logics can be accomplished by changing the form of application of input signals from outside the cells to the input terminals. A chip area of an integrated circuit designed by CAD using a cell library can be reduced and a high speed circuit operation can be attained. The present invention provides remarkable effect for improving performance of an ASIC, a microprocessor, etc., and for reducing the cost of production.
