Abstract
A semiconductor device employs at least one of semiconductor chip groups. The semiconductor device includes a semiconductor chip included in the semiconductor chip groups, and a package. The semiconductor chip includes an information recording region on which is recorded a first piece of identification information indicating to which group of the semiconductor chip groups the semiconductor chip belongs based on a first category. The information recording region includes a plurality of fuses selectively blown in accordance with the first piece of identification information. Indicated on the package is a second piece of identification information indicating to which group of the semiconductor chip groups the semiconductor chip belongs based on a second category. The first and second pieces of identification information are combined together to identify the semiconductor chip from among the semiconductor chip groups.
