Abstract

In order to reduce the chip size of a semiconductor device as well as to separate noises between at least two types of pads having different functions, power supply pins and ground pins are provided on opposite edges of a package with input address pins being arranged therebetween and output data pins being arranged outside the same. Control pins and a nonconnected excess pin are arranged in the center. This allows the package to omit wires and reduce chip size.
