Abstract: A single-slot peripheral component interconnect express (PCIe) card with expanded memory is provided. Embodiments described herein use two rigid circuit boards which are oriented perpendicular to each other. The two rigid circuit boards are connected by a flexible cable, which can be sandwiched between the laminates of the rigid boards. The flexible cable further provides high-speed signal connection and high-power connection between the two rigid boards. In addition, the two rigid boards can be secured by two mechanical retainers. This approach enables a PCIe card to have three or more (e.g., four) dual in-line memory modules (DIMMs) while meeting the PCIe standard for single slot primary side height by placing the DIMM sockets horizontally, thus lowering the overall height of the PCIe card.
