Unbuffered Small Outline DDR3 SDRAM DIMMs (Unbuffered Small Outline Double Data Rate Synchronous DRAM Dual In-Line Memory Modules) are low power, high-speed operation memory modules that use DDR3 SDRAM devices. These Unbuffered DDR3 SDRAM SODIMMs are intended for use as main memory when installed in systems such as mobile personal computers.
