Abstract

PURPOSE:To eliminate up-floating of potential of a non-selective word line, by making a transistor (TR) conductive at the initial state where the word line is selected and up to a specified high potential, then making the TR non-conductive. CONSTITUTION:A TRQ15 turns on before a time T31. A node NO5 is precharged to a potential lower than the power supply potential by 2 times, VT at the same time. At the time T31, the potential on a word line WL5 is risen. Between the time T31 and T32, the selected word line WL5 keeps increasing. Thus, a word line WL6 not selected, is apt to increase from a low potential with the increase in the word line WL5, but since the potential of the node NO5 is the potential of the power supply potential VDD subtracted by 2 times VT, the up-floating of the potential of the word line WL6 not selected is cancelled by turning on of a TRQ14 and it restores to zero potential. Thus, the up-floating of the potential of non-selective word lines are avoided.
