<P>PROBLEM TO BE SOLVED: To obtain a semiconductor storage device in which a conventional circuit easily prevents malfunction such as output noise and latch data break, output delay, etc., due to the data lines of a reading system from a pair of bit lines to an output buffer being influenced by the noise generated by the operation of a peripheral circuit without adding an unnecessary control circuit and an unnecessary layout for noise measurement and deterioration of a memory circuit. <P>SOLUTION: Inputting data lines IDI0 to IDIn connected to input circuits IN0 to INn operation controlled so as to operate only in a fixed period in a write cycle by an input control circuit 6 are alternately arranged so as to shield output data lines IDO0 to IDOn. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
