Virtium Technology Inc. (Rancho Santa Margarita, CA) has added the SSDDR SODIMM to its family of memory and storage product lines. SSDDR is a memory and SSD board design that combines Serial ATA Solid State Drive (SATA SSD) and Double Data Rate Synchronous Dynamic Ram (DDR SDRAM) technologies in a single SODIMM socket for Single Board Computers (SBCs), ETX, COM Express, and ATCA applications. SSDDR serves two independent functions — the NAND Flash module provides localized SATA SSD storage for the operating system (OS), and DDR SDRAM provides the main memory for the CPU. Virtium’s SSDDR solution can be easily adapted and implemented, as both the storage and memory functions share the existing JEDEC standard socket. The SSDDR module and Standard DDR module are interchangeable within the same SODIMM socket.

With the SATA interface as the point-to-point architecture be tween onboard storage devices and the controller, this SATA storage module enables faster boot-up time, quicker access time, and increased data throughput. Data throughput increases two to four times over other embedded SSD and interfaces such as USB (Universal Serial Bus), CF (Compact Flash with IDE interface), and SD (Secure Digital).
