A memory combination includes a first riser board, a second riser board, and a pivotal plate. The first riser hoard includes a plurality of first memory sockets of which long axis directions are parallel to each other. The second riser board includes a plurality of second memory sockets of which long axis directions are parallel to each other. Two end of the pivotal plate are pivotally connected to the first riser board and the second riser board based on an axial direction respectively. When the first and second riser boards rotate to be perpendicular to the pivotal plate, the first memory sockets face the second riser board, and the second memory sockets face the first riser board. The axial direction is perpendicular to the long axis directions of the first memory sockets and the long axis directions of the second memory sockets. |
