Memory card and memory card socket

A memory card comprising a first main surface and a second main surface opposing each other, the memory card comprising:

• a printed circuit board (PCB) establishing the first main surface, the PCB including a plurality of first external connection terminals, the plurality of first external connection terminals on the first main surface;
• a plurality of memory devices stacked on the PCB;
• a memory controller on an uppermost memory device among the plurality of memory devices;
• a molding layer encapsulating the plurality of memory devices and the memory controller, the molding layer establishing the second main surface;
• one or more second external connection terminals electrically connected to the memory controller, the one or more second external connection terminals embedded in the molding layer and exposed by the molding layer at the second main surface, wherein a surface of the one or more second external connection terminals is coplanar with the second main surface;
• a conductive via penetrating the molding layer, the conductive via being connected to one of the second external connection terminals;
• and
• a conductor line extending in a direction parallel to the second main surface, an end of the conductor line being connected to the conductive via and the other end of the conductive line being connected to the memory controller via a bonding wire,
• wherein the plurality of first external connection terminals comprise,
• a first set of the first external connection terminals in a first row, the first row being adjacent to an insertion-side edge of the memory card, the first set of the first external connection terminals including a power supply terminal of a first voltage and a ground terminal, and
• a second set of the first external connection terminals in a second row, the second row being farther apart from the insertion-side edge than the first row, the second set of the first external connection terminals including a power supply terminal of a second voltage and data terminals.
