The semiconductor memory device includes plural core chips that are allocated with different chip identification information from each other and an interface chip that controls the plural core chips. The interface chip receives address information to specify memory cells and commonly supplies a part of the address information as chip selection information for comparison with the chip identification information to the plural core chips. As a result, since the controller recognizes that an address space is simply enlarged, the same interface as that in the semiconductor memory device according to the related art can be used.
