    • 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.
    • 半导体存储器件包括具有存储单元的子存储单元阵列区域,每个存储单元分别连接在沿第一方向延伸的字线和沿着与字线的第一延伸方向正交的第二方向延伸的位线和一个子字线 驱动器区域,设置在副存储单元阵列区域的第一方向的一侧,并且包括激活字线的子字线驱动器。 感测区域设置在副存储单元阵列区域的第二方向的一侧,并且包括响应于通过驱动信号线传送的信号而对位线进行预充电的均衡器,以及至少一个第一控制信号驱动器,其激活 响应于通过控制信号线传送的信号的反相控制信号线。 配置在副字线驱动器区域和感测区域之间的交叉点处的连接区域,其中反相控制信号线连接到驱动信号线。
