Abstract
To provide a semiconductor memory device that can be mounted on both sides of a circuit board having a relatively simple wiring pattern and can be manufactured at a low cost, the semiconductor memory chip of the present invention includes a plurality of memory cells, a control circuit formed on a semiconductor substrate, a plurality of electrode pads are formed on one of the principal planes for the purpose of input and output of signals to/from the control circuit, wherein at least a pair of the electrode pads consist of selective connection electrode pads that can drive the control circuit by selecting and connecting either one thereof, and the two selective connection electrode pads are disposed on both sides of a longitudinal or lateral chip centerline on the one principal plane.
