Abstract
A semiconductor device according to the present invention includes plural core chips CCto CCto which mutually different pieces of chip identification information LID are allocated, and an interface chip IF that controls the core chips CCto CC. The interface chip IF receives address information ADD for specifying a memory cell, and supplies in common a part of the address information to the core chips CCto CCas chip selection information SEL to be compared with the chip identification information LID. With this configuration, it appears from a controller that an address space is simply enlarged. Therefore, an interface that is same as that for a conventional semiconductor memory device can be used.
