Abstract: A storage device includes a printed circuit board (PCB) with attached semiconductor chips, each including a memory, and with at least one wire coupling the semiconductor chips. The storage device includes a case including a first case surrounding a top portion of the printed circuit board and a second case surrounding a bottom portion of the printed circuit board. A sidewall of the first case and a protrusion of the second case form a concavo-convex structure. The sidewall of the first case and the protrusion of the second case cover a side of the printed circuit board.
