A memory card is provided to include a substrate having two pairs of edges facing each other, a plurality of first row terminals that are arranged adjacent to an edge at an insertion side of the substrate and include a first voltage power terminal for applying a first voltage and a first ground terminal, a plurality of second row terminals that are spaced farther apart from the edge at the insertion side than the plurality of first row terminals and include a second voltage power terminal for applying a second voltage and first data terminals, and a plurality of third row terminals that are spaced farther apart from the edge at the insertion side than the plurality of second row terminals and include second data terminals.

Memory card

A method of operating a mobile device including an embedded storage having a first capacity includes recognizing, in an application processor of the mobile device, that an external storage is connected to the mobile device, and measuring a performance of the external storage in the application processor of the mobile device. When the performance is equal to or greater than a reference value, the embedded storage and the external storage are constituted into one parallel processing storage, and workload is allocated by memory control module of the application processor to the embedded storage and the external storage based on a first performance of the embedded storage and a second performance of the external storage.

Methods of operating mobile devices and mobile devices

A digital-to-analog converter includes an amplifier including at least two input terminals corresponding to a non-inverting input terminal; and a chopping unit performing a chopping operation between voltages provided to the at least two input terminals corresponding to the non-inverting input terminal. The digital-to-analog converter has an X+Y bit structure and removes an offset by performing an interpolation chopping operation and/or a main buffer chopping operation at the same time. The digital-to-analog structure can be embodied in a small area and can process high bit image data.

Digital-to-analog converter

Memory card adapters and/or a memory apparatuses may be provided. For example, a memory card adapter including a main housing section that corresponds to a memory card socket of a first standard, the main housing section including a card housing section, the card housing section configured to house a memory card of a second standard different from the first standard therein, a first surface of the main housing section defining a through-hole, the through-hole configured to expose a connection pin of the memory card to be housed in the housing section to an outside of the housing section, and a second surface of the main housing section defining a card insertion hole, the second surface being different from the first surface, the card insertion hole configured to receive the memory card into the card housing section may be provided.

Memory card adapter and memory apparatus

Disclosed are a card socket device and an electronic apparatus including the same. The card socket device includes a seat portion configured to receive an attachable card; and one or more connection terminal portions formed in the seat portion and configured to form an electrical connection with one or more connection pads formed in a bottom surface of the attachable card, wherein the seat portion is configured such that a space accommodating the attachable card is upwardly opened.

Card socket device and electronic apparatus including the same

A memory card identification device, a host device using the memory card, and a memory card are provided. The memory card identification device includes: a card socket comprising a single card slot through which at least two kinds of memory cards can be inserted and a target port disposed to be in contact with any one kind of a target memory card based on an external characteristic difference between different kinds of memory cards; and a card type detector configured to determine a type of a memory card inserted in the card socket by using a contact state signal of the target port.

Memory card indentification device, host device and memory card using the same

In one embodiment, the memory device includes a first memory area and a second memory area. The first memory area stores secure data. The first memory area is inaccessible by an external device. The second memory area is configured to store encrypted secure data. The second memory area is accessible by the external device, and the encrypted secure data is an encrypted version of the secure data in the first memory area.

Memory device which protects secure data, method of operating the memory device, and method of generating authentication information

A storage system that enables the use of a plurality of keys respectively stored in a plurality of storage units of a storage device is provided. The storage system includes a storage device including a first storage unit and a second storage unit that are recognized as a single storage device, wherein the first storage unit is configured to store a first key, the second storage unit is configured to store a second key different from the first key, and a controller is configured to transmit to the storage device one of a first key-read control signal that includes information about the first storage unit and a second key-read control signal that includes information about the second storage unit and receive the first key and the second key as identification information of the storage device in response to the first key-read control signal and the second key-read control signal, respectively.
