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 UDIMMs, 200-pin SO-DIMMs are also available for compact systems. These form factors are not interchangeable with DDR, DDR3 or DDR4.

Micron and ATP To Collaborate on DDR2 Continuity Program
Partnership Agreement Ensures Legacy DRAM Module Supply Stability
Recognizing the importance of obsolescence mitigation in embedded and industrial systems, two of the biggest names in advanced storage, memory and semiconductor technologies have teamed up to ensure the continuous supply of legacy DDR2 memory modules in the market. ATP, a leading manufacturer of high-performance industrial memory and storage solutions, will collaborate with global semiconductor leader Micron Technology, Inc. to continue manufacturing Micron DDR2 SO-DIMMs, UDIMMs and RDIMMs after Micron announced end-of-life (EOL) notices for these modules.
According to the collaboration agreement, ATP will produce DDR2 DRAM modules for customers that cannot upgrade to newer-generation platforms and still maintain the use of platforms supporting these memory types. With DDR2 still widely deployed in the US, Japan and Europe, ATP and Micron expect these markets to benefit significantly from the consistent supply of DDR2 memory for industrial/embedded systems installed in high-reliability and mission-critical environments. All modules will be manufactured, tested and validated by ATP, according to the equivalent specifications and testing/validation processes of the respective Micron part number.
"Micron is dedicated to maximizing customers' infrastructure investments by ensuring prolonged support for legacy systems and applications. Our proven partnership with ATP gives our customers the benefit of receiving similar Micron products and services to support their current platforms while ATP ensures the stability of their operations well into the future," said Kris Baxter, vice president, Micron Technology, Inc.
The DDR2 Continuity Program will be implemented on a staggered basis within three manufacturing phases. DDR2 DRAM modules from ATP will be available in select form factors and densities starting Q4 2018.
