DDR2 and SDRAM

Industrial DDR2 SDRAM improvements over first gen. DDR included: reduced clock speed resulting in higher bus speed. 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. DDR2 generation also saw the introduction of additional form factors as listed below.

Virtium contributed to the advancement of the DDR2 generation with the development of ECC VLP RDIMM targeted at AdvancedTCA applications.

SDRAM (Synchronous Dynamic Random Access Memory) became a JEDEC standard in 1993, and became the dominant memory interface by the year 2000. SDRAM was targeted at the 66 MHz and 100 MHz bus speeds available on PC motherboards at the time and was a successor technology to EDO DRAM.

Virtium continues to offer this tried-and-true early industry standard for legacy industrial memory customer designs.
