SERIAL ADVANCED TECHNOLOGY ATTACHMENT DUAL IN-LINE MEMORY MODULE DEVICE AND MOTHERBOARD SUPPORTING THE SAME

摘要

A motherboard assembly includes a motherboard and a serial advanced technology attachment dual in-line memory module (SATA DIMM) device. The motherboard includes an expansion slot, a first universal serial bus (USB) connector, a power connector, and a central processing unit (CPU). The expansion slot includes a correct-insertion protrusion, first power pins connected to the power connector, and first signal pins connected to the CPU. The SATA DIMM device includes a circuit board. A second USB connector, a signal converting chip, a power circuit, a control chip, and a number of storage chips are all arranged on the circuit board. A notch in the circuit board receives the correct-insertion protrusion. An edge connector is arranged on a bottom side of the circuit board and includes second power pins connected to the power circuit, and second signal pins connected to the control chip.
