DDR2 SDRAM

The memory clock speed of the industrial DDR2 SDRAM was reduced by half compared to the DDR1 generation for a given bus speed. This change resulted in higher bus speed for an equivalent memory clock rate at the cost of increased latency. The operating voltage was reduced from 2.5 Volts to 1.8 volts to reduce power consumption and facilitate the use of smaller semiconductor fabrication processes. The DDR2 generation also saw the introduction of additional form factors such as the 214 pin MicroDIMM with ECC, the 244 pin Mini-DIMM, and features such the Fully Buffered DIMM (FB-DIMM), Low profile DIMM and ECC SODIMM.

Virtium has continually contributed to the advancement of the DDR2 generation with the development of ECC VLP RDIMM targeted at AdvancedTCA applications. Virtium also works with organizations such as JEDEC to create products that meet the needs of our embedded system OEM customers.
