    摘要: A semiconductor memory device capable of reading out data at a higher speed and occupying a decreased chip-area is provided. The device includes a bit line selection circuit including a plurality of first transistors for selecting a plurality of bit lines according to a plurality of column selection signals generated based on address signals, a bit line charging circuit including a plurality of second transistors for charging the plurality of bit lines, respectively, and a bit line grounding circuit including a plurality of third transistors for connecting the plurality of bit lines with a ground potential. This enables the decrease in a charging time during a bit line precharging operation and a discharging time during data reading-out operation. Further, by grounding adjacent bit lines that are not involved in a precharging or reading-out operation so that they have a ground potential, it is also possible to minimize bit line intervals without causing a malfunction due to an increase in capacitances between the bit lines.

    摘要: A semiconductor memory cell is implemented in which the area of a row selection circuit is reduced and the effects of exposure, etching, and so on performed during manufacture are eliminated. The semiconductor memory device is provided with word line selection circuits connected with a row address signal line to select some desired word line according to an address input and dummy word line potential fixation circuits connected to word lines for dummy memory cells. As in the case of the word line selection circuits, the dummy word line potential fixation circuits each include a NAND gate NANDR(i) (i=−1, 0, m+1, or m+2) and an inverter INVR(i) (i=−1, 0, m+1, or m+2). The inputs of the dummy word line potential fixation circuits are connected with a row address signal line such that the word lines for the dummy memory cells are maintained in a non-selected state at all times. These make it possible to make the circuits which selectively drive all the word lines identical with each other in configuration, reduce the area of the row selection circuit, and eliminate the effects of exposure, etching, and so on during manufacture.

    摘要: A semiconductor device is provided for outputting data read from a read only storage device. The semiconductor device includes a read only storage device including memory cells, an address signal line for transmitting an address signal to each read only storage device, and a switching device to which the address signal is inputted. The address signal indicates an address of memory cells storing data to be read. The switching device includes an address storage circuit, a bit storage circuit and a switching storage circuit. The address storage circuit stores address information of a defective memory cell of the read only storage devices and detects whether or not memory cells storing data selected by an address signal includes a defective memory cell. The bit storage circuit stores bit information indicating which bit of data stored in memory cells including a defective memory cell is defective, and outputs a controlling signal. The switching circuit inputs the controlling signal and data outputted from a read only storage device which is selected by an address signal and outputs the data from the read only storage device. The switching circuit inverts a defective bit of the data outputted from the read only storage device in response to receipt of the controlling signal from the bit storage circuit and outputs data whose defective bit is inverted instead of the data outputted from the read only storage device.

    摘要: A semiconductor memory device includes a memory cell array, a charge circuit which compensates for OFF leakage current developed at selected bit lines, a reset circuit having a ground potential corresponding to a potential at non-selected bit lines, a read circuit constituted by a plurality of transistors whose gates are connected to the bit lines, and a bit line precharge circuit which charges the selected bit lines for a fixed time period. As a result of adopting such a configuration, there is no need to provide a transmission gate, such as a column decoder, to a charging path between the read circuit and the bit lines, so that a low-power supply voltage operation can be effected without the influence of a substrate bias effect.
