摘要： The threshold voltage of bit line percharge/equalize MOS transistors is smaller than that of normally ON type bit line pull-up transistors. With this feature, there is no current flows through a bit line from power source V.sub.DD during a read-out operation. The voltage difference between a pair of bit lines can be increased at high speed, thereby increasing the read-out speed.

摘要： A static semiconductor memory comprises a word line, a memory cell array divided into a plurality of blocks in an extending direction of the word line, each block including a plurality of sections each of which includes a plurality of static memory cells, a controller, a section data line provided for each section, first sense amplifiers, a block data line provided for each block, second sense amplifiers, a main data line and a latch circuit for latching data on the main data line. The controller selects an arbitrary section in the memory cell array at the time of data readout and controls the reading of data from memory cells included in the selected section. The section data line is supplied with data read out from the memory cells. The first sense amplifiers, coupled at their input terminals to the section data line, are activated only when their associated section is selected. The individual first sense amplifiers in the same block have their output terminals commonly coupled to the block data line. Each second sense amplifier, coupled at its input terminal to the associated block data line, is activated only when the sections belonging to that block are selected. The second sense amplifiers have their output terminals commonly coupled to the main data line.

摘要： In a semiconductor memory device with normal word lines and spare word lines, a partial decoder receives and decodes a predetermined two of the bit signals of the original logic levels of an address signal, and two of the bit signals of the complementary logic levels, which correspond to the predetermined two bit signals, and outputs different signal combinations of the predetermined two bit signals and the two corresponding bit signals. A spare word line selecting circuit receives the different signals and selects one of the different signals in order to select a spare word line which corresponds to a normal word line to which a defective cell is connected. The partial decoder may be used for both the normal word line selection and the selection of spare word lines. With a device constructed in such a manner, bit signals of an address signal are not directly input to the spare word line selecting circuit, but rather signals of different bit signal combinations are input to it. The spare word line selecting circuit merely selects signals of different combinations, and does not need the partial decoding of the address signal. Therefore, the chip area required for wiring may be remarkably reduced when compared with the conventional memory device.

摘要： In a selected column, a pull-up transistor pair is not selected but, instead, a transmission gate transistor pair is selected. In the read mode, the transmission gate transistor pair serves as pull-up loads between the bit line pair. However, the transmission gate transistor pair is kept off until the voltage across the bit line pair is decreased from the power supply potential level to the threshold voltage level of the transmission gate transistors. Therefore, no DC current path is formed in the bit line pair when the voltage across the bit line pair is within a range from a voltage equal to the power supply potential level to a potential lower than the power supply potential by an amount equal to the threshold voltage level, and the rate of increase of a potential difference across the bit line pair is determined by a pull-in current of the memory cell. Therefore, a high-speed sense operation can be realized. In the write mode, the transmission gate transistor pair serves a bit line pull-up function. Since no normally-ON bit line load transistor is arranged, no direct current path including the bit line pair is present, and hence, low power consumption can be achieved.

摘要： This invention relates to P- and N-well regions where inverters constituting an SRAM cell are formed. The P-well region is divided into two parts, which are laid out on the two sides of the N-well region. Boundaries (BL11, BL12) are formed to run parallel to bit lines (BL, /BL). With this layout, diffusion layers (ND1, ND2) within the P-well regions can be formed into simple shapes free from any bent portion, reducing the cell area.

摘要： A first and second barrel shifters (BSA0 and BSA1) are connected directly without intervening any pipe-line register between the two, and a sense amplifier (R3A0) is provided at an output side of the second barrel register (BSA1). Further, the circuit patterns of the first and second barrel shifters are formed being overlapped with each other in such a way that the elements of one of the first and second barrel shifters are formed at the dead space of the other of the two barrel shifters to reduce the pattern area. In the shift circuit and the variable-length decoder, the data lines of the barrel shifters can be minimized in size and width.
