Abstract
An I/O module configured to operate in a memory module socket and method for extending a memory interface are generally described herein. The I/O module may include a serial-presence detection (SPD) device to indicate that the I/O module is an I/O device and to indicate one or more functions associated with the I/O module. The I/O module may also include a serial data controller to communicate serial data in accordance with a predetermined communication technique with a configurable switch of a host system over preselected system management (SM) bus address lines and unused system clock signal lines of the memory module socket. The predetermined communication technique may include a peripheral component interconnect express (PCIe), a Serial Advanced Technology Attachment (SATA), a Serial Attached Small Computer System Interface (SAS), a universal-serial bus (USB) or a switched-fabric (InfiniBand) communication technique.
