PURPOSE:To increase an operating speed without increasing a whole area by removing a dead space. CONSTITUTION:On the intersecting part between the line of word driving circuit and the line of sense circuit parts, first driving circuits (Da11, Da12) assigned for driving sense amplifier circuits (SA11-SA13) of sense circuit parts (SC11-SC13) and second driving circuits (Db11, Db12) assigned for driving precharging circuits (PC11-PC13) and transfer circuits (TG11-TG13) are alternately and successively arranged. A set of the first and the second driving circuits drives one sense circuit part. |
