Abstract
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 capable of being electrically connected to an external device, wherein the controller is operable in a universal flash storage (UFS) mode and in a first sub-mode other than the UFS mode.
Claims9
An electronic system comprising:
- a controller;
- an input/output device;
- a memory;
- an interface that electrically communicates with an external device;
- and
- a bus that communicatively connects the controller, the input/output device, the memory, and the interface to each other,
- wherein the interface comprises a card socket configured to accommodate a memory card,
- wherein the card socket comprises a first connection pin connectable to a card detection terminal of a universal flash storage (UFS) card when the UFS card is inserted in the card socket, and
- wherein, when the memory card is inserted in the card socket, the controller is configured to detect the memory card as a UFS card when a voltage of the first connection pin is lower than a first reference voltage and to supply a first voltage to a power supply terminal of the UFS card, and is configured to when the voltage of the first connection pin is in a floating state, apply a second voltage to a second connection pin and detect the memory card as a micro secure digital (SD) card or a peripheral component interconnect express (PCIe) card based on a voltage of a third connection pin.
