A collaboration of embedded system integration

A collaboration among Virtium, Swissbit, and LiPPERT Embedded Computers working through the SFF-SIG resulted in a module with a pin definition that closely resembles that of a DDR3 standard DIMM. The pin definition leverages a high-performance 240-pin SMT connector system that uses standoffs with screw attachments to firmly hold the XR-DIMM memory module to the motherboard. Additionally, the pin definition includes a SATA interface to enable the development of dual-function modules that contain both DDR3 and NAND flash for a combined memory and solid-state drive storage implementation from a single socket. Future standards for combination SATA and DDR3 modules are planned. These embedded computer systems needed a small form factor, extremely rugged DDR3 module. This standard relieves designers from the former limitations of commercial-grade products that required soldering, straps, glue, or tie-downs to secure the module.
