Card-type solid state drive

A card-type solid state drive (SSD), comprising:

• a substrate that includes an insertion edge, a first edge, and a second edge, the insertion edge extending in a first direction, the first and second edges being adjacent to the insertion edge and extending in a second direction perpendicular to the first direction;
• a protrusion at the first edge;
• and
• first-row functional terminals, second-row functional terminals, third-row functional terminals, and thermal terminals that are on a surface of the substrate,
• wherein the first-row functional terminals are linearly arranged along the first direction, the first-row functional terminals including a first power terminal and a plurality of first data terminals,
• wherein the second-row functional terminals are spaced apart in the second direction from the first-row functional terminals and are linearly arranged along the first direction, the second-row functional terminals including a second power terminal and a plurality of second data terminals,
• wherein the third-row functional terminals are spaced apart in the second direction from the second-row functional terminals and are linearly arranged along the first direction, the third-row functional terminals including a third power terminal and a plurality of command terminals,
• wherein the thermal terminals are arranged in at least one row and are spaced apart in the second direction from the first-row functional terminals, the second-row functional terminals, and the third-row functional terminals,
• wherein the first, second, and third power terminals are adjacent to the first edge, and
• wherein one of the thermal terminals that is adjacent to the first edge is not linearly arranged along the second direction with the first, second, or third power terminal.

A card-type solid state drive (SSD), comprising:

• a substrate that has a first surface and a second surface facing each other;
• a memory controller and a nonvolatile memory device that are on the first surface;
• a plurality of functional terminals on the second surface;
• and
• a plurality of thermal terminals on the second surface,
• wherein the substrate further includes an insertion edge, a first edge, a second edge, and a protrusion at the first edge, the insertion edge extending in a first direction, the first and second edges being adjacent to the insertion edge and extending in a second direction perpendicular to the first direction,
• wherein the functional terminals include first-row functional terminals including a first power terminal, second-row functional terminals including a second power terminal, and third-row functional terminals including a third power terminal adjacent to a first edge of the card-type SSD,
• wherein a thermal terminal closest to the first edge is farther from the first edge than each of the first, second and third power terminals, and
• wherein at least one of the thermal terminals overlaps the memory controller or the nonvolatile memory device.
