Abstract
A semiconductor memory device includes a sub memory cell array region having memory cells each connected between word lines extending in a first direction and bit lines extending in a second direction that is orthogonal to the first direction of extension of the word lines and a sub word line driver region disposed at a side of the sub memory cell array region in the first direction and including sub word line drivers that activate the word lines. A sensing region is disposed at a side of the sub memory cell array region in the second direction and including an equalizer that precharges the bit line in response to a signal transferred through a drive signal line and at least one first control signal driver that activates an inverted control signal line in response to a signal transferred through a control signal line. A conjunction region disposed at an intersection between the sub word line driver region and the sensing region, in which the inverted control signal line is connected to the drive signal line.
