DDR2 for industrial use

DDR2

Key features
  • Density: 1GB to 8GB
  • Chipkill support

FB-DIMM

  • Low power and low voltage options
  • Apple FB-DIMM

DDR2 supersedes the original DDR specifications with data transfer speeds up to 800 MT/s. The memory clock speed of the industrial DDR2 SDRAM was reduced by half compared to first-generation DDR, enabling DDR2 to effectively operate at 2X the DDR bus speed. 

Apart from faster operation, DDR2 also consumes less power than its predecessor. With its operating voltage reduced from 2.5V to 1.8V, DDR2  cuts overall power consumption.

ATP DDR2 modules are available in several form factors suitable for diverse applications, including 240-pin full-size DIMMs, 200-pin SO-DIMMs, 244-pin Mini-DIMMs, and 240-pin FB-DIMMs. Very Low Profile (VLP) DIMMs and Mini-UDIMM options are also available for compact systems. These form factors are not interchangeable with DDR, DDR3 or DDR4.

Micron and ATP collaborate to maintain stable supply of legacy DDR2 memory modules

• ATP will manufacture, test and validate the modules according to the equivalent specifications and testing/validation processes of the respective Micron part number, so Micron customers will receive similar Micron products and services to support their current platforms.

• ATP commits to ensure the steady supply of these modules to sustain the memory requirements of customers using platforms that support these memory types.

• The DDR2 Continuity Program will be implemented on a staggered basis within three manufacturing phases. ATP Electronics will continue to manufacture the following Micron legacy DDR2 DRAM modules, which will be available in select form factors and densities starting Q4 2018. Please check with your ATP contact for specific module configurations with ATP longevity extension.
