    摘要: An arrangement which is particularly effective for decoders in semiconductor memory circuits which use, for example, common NMOS to receive one input for a plurality of logic decoder gates is provided includes a plurality of logic gates each having a first input terminal for respectively receiving first input signals, and each being coupled to a common node. In one embodiment, first and second switching elements are also coupled to the common node. The first and second switching elements are both coupled to a second input terminal for receiving a second input signal which is common to the plurality of logic gates, and both operate complementary to one another in response to the second input signal. An improved read/write arrangement is also provided for such semiconductor memory circuits which includes circuitry to prevent connection of a common read line to the data lines during the writing operation. This enhances the writing speed by removing the load of the common read line during writing.

    摘要: A static RAM comprises: column select circuits for connecting a plurality of pairs of corresponding complementary data lines at a unit of each pair with common complementary data lines; and redundant circuits each composed of the complementary data line pair and the column select circuit corresponding to the unit. Load MOSFETs of the complementary data lines are arranged close to the column select circuits to inhibit the column selecting operations by a decoder circuit and turn off the load MOSFETs when fuse means is cut. An access to a defective address is detected by a redundant decoder stored with the defective address, when the fuse means is selectively cut, to select the column select circuits of the redundant circuit.
