PURPOSE:To prevent the reading of error data by a sense amplifier by easily adjusting the increasing amounts of the potential of a bit line through a dummy capacity due to the selection of a pseudo word line without adjusting the capacity value of the pertinent dummy capacity. CONSTITUTION:A sense amplifier SA is connected between a pair of bit lines BL and the inverse of BL, and a storage cell Cm is connected between either the bit line BL or the inverse of BL and a word line WL. A word line driving circuit WD which operates at the time of selecting the pertinent word line Wl, is connected with the word line WL, and a dummy capacity DC is connected between either the bit line BL and the inverse of BL, and a pseudo word line DWL making a pair with the word line WL. The pseudo word line DWL is connected through an output level adjusting circuit 1 with a pseudo word line driving circuit DWD which operates synchronously with the word line driving circuit WD, and which selects the above mentioned pseudo word line DWL. |
