Memory card and electronic apparatus including the same

A memory card comprising:

• a substrate having a first pair of side edges extending in a first direction and a second pair of side edges extending in a second direction perpendicular to the first direction;
• first row terminals arranged adjacent to an insertion side edge of the substrate and including a first power terminal, the insertion side edge being one of the first pair of side edges;
• second row terminals arranged further from the insertion side edge than the first row terminals and including a second power terminal and a first data terminal;
• and
• third row terminals arranged further from the insertion side edge than the second row terminals and including a second data terminal,
• wherein at least one terminal among the first, second, and third row terminals includes a recess area in an exposed surface of the at least one terminal.

An electronic apparatus comprising:

• a socket;
• a tray detachable from the socket and having an accommodation space configured to receive a memory card;
• the memory card;
• and
• socket pins configured to electrically connect to the memory card,
• wherein the memory card includes,
• a substrate having a first pair of side edges extending in a first direction and a second pair of side edges extending in a second direction perpendicular to the first direction,
• first row terminals arranged adjacent to an insertion side edge of the substrate, the first row terminals including a first power terminal, the insertion side edge being one of the first pair of side edges, and
• second row terminals arranged further from the insertion side edge than the first row terminals, the second row terminals including a second power terminal,
• wherein each terminal among the first and second row terminals includes a recess area in at least part of an exposed surface, and
• wherein the socket pins includes first row socket pins and second row socket pins, each of the first row socket pins including a head portion configured to electrically contact one of the first row terminals by being inserted in the recess area of the one of the first row terminals, each of the second row socket pins including a head portion configured to electrically contact one of the second row terminals by being inserted in the recess area of the one of the second row terminals.
