A memory card includes a card substrate on which a controller and a memory device are mounted, and a card enclosure that accommodates the card substrate and exposes terminals for electrical connection to an external device. The controller is operable in a universal flash storage (UFS) mode and in a first sub-mode other than the UFS mode. The terminals that are exposed include a UFS terminal group according to a UFS standard, and a first sub-mode terminal group. The UFS terminal group includes first row terminals arranged adjacent to an insertion side edge of the memory card and second row terminals arranged apart from the insertion side edge such that the first row terminals are provided between the second row terminals and the insertion side edge. The first sub-mode terminal group is adjacent to the first row terminals.
