    摘要: An LSI semiconductor memory device in which errors in reading out memory cells connected to outermost bit lines of a memory cell array of the device are substantially eliminated. In accordance with the invention, this is done by making capacitances associated with the bit lines of respective ones of the memory cell array substantially equal to one another. To accomplish this, the configuration of an inside portion of wiring other than the bit lines of the array is made the same as that of the bit lines, and the distance between the outermost bit line and the other wiring is made equal to the distance between adjacent ones of the bit lines.

Its power supply node is connected through a switch to a first power supply (Vss). Data nodes of a second flip-flop are connected to a second pair of folded bit lines. Its power supply node is connected through a switch to the first power supply (Vss). A power supply node of a third flip-flop is connected through a switch to a second power supply (Vcc). Data nodes of the third flip-flop are coupled through a first pair of transfer gates to the first pair of the folded bit lines, and through a second pair of transfer gates to the second pair of the folded bit lines. Coupling the first to the third flip-flops forms a first sense amplifier and coupling the second to the third flip-flops forms a second sense amplifier.

    摘要: In a memory cell comprising a data cell array and a parity cell array, an error checking.multidot.correcting circuit is connected to each of the arrays through a selector. The selector is constituted by transistors connected to each of the bit lines in the memory cell. The number of circuit elements constituting the error checking.multidot.correcting circuit corresponds to one-half of the number of the bit line pairs included in the data cell array and the parity cell array. In an error correcting mode, half of the data appeared on the bit line pairs in data cell array and the parity cell array are transferred to the error checking.multidot.correcting circuit by the selector, so that the errors are corrected. Thereafter, the data of the remaining half of the bit line pairs are processed in the same manner. Therefore, the number of circuit elements of the error checking.multidot.correcting circuit can be reduced compared with the prior art, improving the degree of integration of the device.

    摘要: In a semiconductor memory device of a redundancy configuration having lines (rows or columns) of main memory cells and a line of spare memory cells made to substitute a defective line responsive to the address of the defective line, a comparator compares an address input to the memory device, with the address of the defective line which has been programmed in it, and a spare line selector selects the spare line when the input address is found to coincide with the programmed address. The comparator comprises a dynamic NOR gate having discharge paths each formed of a gate element receiving a bit or its inversion of the input address to be opened or closed depending on the value of the particular bit of the input address currently applied, and a PROM element in series with the gate element. The dynamic NOR gate has a first node forming an output thereof and a second node, each of the series connections of the PROM element and the gate element is connected across the first and the second nodes. The potential on the second node is caused to be identical with the potential on the first node during the precharge period.
