Abstract
There are provided a sense amplifier driving circuit 900 applying a potential VCC/2 to wirings PSA and NSA when a block selecting signal BS0 is at a 'L', and applying a potential VCC to the wiring PSA via a pMOS transistor 91 and applying a grounding potential to the wiring NSA via an nMOS transistor 94 when the block selecting signal BS0 is at a 'H', and a LDB reset circuit 901A connected between the wiring PSA and a local data bus line pair LDB0 and *LDB0 and including pMOS transistors 95A and 96A which are closed/opened in correspondence to the open/closed state of a column gate 700.
