A semiconductor memory device includes a memory array section configured to serve as an information storage area and an interface section configured to interface between an external memory controller and the memory array section, the memory array section and the interface section being sealed in a package. The interface section includes a plurality of interface modules configured to correspond to a plurality of memory types on a one-to-one basis, and a clock generation section configured to generate a plurality of clock signals based on a system clock signal supplied by the external memory controller. The generated clock signals are used by the plurality of interface modules. The interface section further includes a mode interpretation section configured to interpret an input mode designation signal as indicative of one of the memory types in order to output a mode signal denoting the interpreted memory type. |
