Abstract
Column signals CL ˜CLm generated in a Y decoder circuit are selectively output to a sub-register block S or a resister block R, based on enabling signals SEN and REN. Then, write-in data is stored in the sub-register block S or the resister block R or read-out data is obtained from the sub-register block S or the resister block R. By structuring in this way, it is possible to reduce the scale of a circuit of a semiconductor device and lessen the chip size.
