SEMICONDUCTOR MEMORY AND ITS CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To provide a semiconductor memory whose chip area can be reduced. SOLUTION: A control circuit is constituted so that a sense amplifier 25a is activated after a column gate 71 is turned on at the time of a write operation and data from a data bus line DB are applied to one side of the input/output terminal of the sense amplifier 25a connected to a pair of bit line BL, /BL. The activated amplifier 25a amplifies the potential of the bit line BL connected to an input/output terminal T1 to which data are supplied up to a potential of the data and amplifies the potential of an inversion bit line /BL up to the inversion potential of the data.
