    摘要: A read only memory includes a memory cell matrix, a word line decoder, a column decoder, and an output buffer. Said memory cell matrix is comprised of a plurality of submatrices, each of which is formed by dividing bit lines into a plurality of parts. Each sub-matrix contains the same word lines. Said word line decoder produces a signal to select a certain sub-matrix in addition to signals to select a certain word line. Said column decoder produces signals to select one column from each of said sub-matrix. Said output buffer has a column selection circuit having a plurality of stages. The first stage selects one column from each of said sub-matrices according to said signals from said column decoder. The second stage selects one column among said selected columns according to said signal to select a certain sub-matrix produced in said word line decoder. Thus, a particular memory cell is selected from the memory cell matrix. In this case, the number of memory cell transistors connected to each bit line is greatly reduced. The data readout speed of this ROM is, therefore, greatly improved in this invention.

    摘要: Disclosed herein is an adder which comprises a Manchester-type adder circuit and which can operate as fast as a dynamic adder, and can perform addition during the clock cycle as a static dynamic adder. Hence, the adder serves to increase the operating frequency of the system in which it is incorporated. The adder further comprises two initializing signal output circuits, each designed to generate an initializing signal in response to predetermined data supplied before the Manchester-type adder circuit starts performing each operation, thereby to initialize the Manchester-type adder circuit.

    摘要: A dynamic barrel shifter has a data input portion, a data shift portion, and a shifted data output portion including sense inverters which are set at threshold voltage higher than a half of the power source voltage. The sense inverters are provided for every transmission route for each binary code. The dynamic barrel shifter also has a pre-charge portion for pre-charging the data shift portion and the shifted data output portion prior to the input of data. The pre-charge portion includes a first power source voltage applying circuit for applying electric potential lower than the power source voltage to the data shift portion through first gate elements from the power source, and a second power source voltage applying circuit for applying electric potential equal to the power source voltage to the input side of the shifted data output portion through second gate elements.
