Virtium’s DRAM memory modules are designed to meet mission-critical, extreme temperatures, high-reliability and long life requirements for the most demanding embedded designs. Our extensive engineering expertise enables us to deliver small-form-factor memory in the highest density, lowest profile and smallest form factors possible. Virtium has applied patented design and component stacking techniques to improve system reliability and increase MTBF.
Virtium also offers advanced small form factor ruggedized features such as thermal heat spreaders, conformal coating, thermal sensors and under fill. This technology enables our memory modules to withstand the industrial temperature, shock and vibration requirements of many embedded systems.
As one of the first manufacturers to offer industrial DDR4 memory, Virtium enables embedded industrial OEM customers early test and development access to the lower power, high bandwidth and density benefits (up to 32GB) of this latest DRAM technology. Delivering significant power savings of up to 40% and up to twice the bandwidth over DDR3, Virtium’s industrial DDR4 modules are excellent solutions for server blades, networking and telecom applications.

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.

DDR SDRAM was the follow-on technology to SDRAM and is the predecessor to subsequent generations of DDR2 and DDR3. DDR provides a lower voltage level and higher data transfer compared to SDRAM. The voltage level is reduced from 3.3 volts to 2.5 volts and the memory module provides a data transfer on both transitions of the clock signal. This produces more data transfers for a given clock speed, but with the drawback of increased latency.
Virtium supports industrial DDR modules in a wide range of configurations and features that are available in 184 and 200 pin DIMM and 200 pin SODIMM form factors.

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.
