摘要：
A semiconductor memory device includes two subcircuits each including a memory circuit, a semiconductor circuit, and a logical circuit. Connection pads are divided into only two parallel rows located along the outer periphery of the semiconductor memory device. Each of the pads may include a probe region against which a probe is pressed for testing the semiconductor memory circuit, and a wire region to which a wire is connected upon packaging.
