DDR2

Key Features

  • Density: 256 MB to 8 GB
  • Chipkill support
  • Micron Continuity Program

Description

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 up to 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, and 244-pin Mini-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.
