Abstract
According to one embodiment, a semiconductor memory card includes a first pin group which includes a plurality of pins arranged in a line at an end portion on a side of an inserting direction into a connector and part of which is used both in a first and second modes; and a second pin group which includes a plurality of pins including at least two pin pairs for differential signal, is arranged so that a ground is positioned on both sides of each of the pin pairs for differential signal, and is used only in the second mode. In the second mode, among the respective pins configuring the first pin group, any of adjacent two pins are changed to a pin pair for differential clock signal, and a function of remaining pins of the first pin group is stopped.
