Abstract
The access time required to read data from a synchronous memory device is shortened. Drivers (31) drive sub-word lines (30) connected to the gates of pass transistors in memory cells (1). An address decoder (34) selectively activates main word lines (32) prior to the falling of a clock (T). The drivers (31) having a first input terminal connected to the activated main word line (32) activate the main word line (32) at the time when the clock (T) at their second input terminal falls.
