Micron DDR2: Maximize the Life—and Performance—of Your Design
We’re doing all we can to help you get the very most out of your designs. For instance, now we’ve raised the bar for performance by offering DDR2 memory that reaches speeds of DDR2-1066. Increasing the performance of an established product line like DDR2 can ultimately maximize the lifespan of a design—which means your design can still deliver for years come.
Our DDR2 line also offers a range of other options. From 1.5V, 1.55V, and 1.8V voltages to RoHS 6/6-compliant components, we’re firmly committed to providing power-saving products. We also maintain a full set of products that are 5/6 compliant for industries that have exempt applications. Bottom line—with such a range of high-performance DDR2 solutions to choose from, you can get what you need when you need it.

Our DDR2-1066 memory leads the industry with the fastest speeds for component and module devices. At 1066 Mb/s, these devices easily meet industry demand for increased speeds and improved bandwidth—and they do it without requiring any system redesign.
Maximize your energy savings at the microchip level by using energy-efficient Aspen Memory FBDIMMs. Other than the voltage change, using these 1.5V DDR2 FBDIMMs is transparent to your system. The performance, timing, and other operating requirements for 1.5V FBDIMMs are identical to 1.8V FBDIMMs; the 1.5V parts just consume considerably less power.
