Crucial Techology, a division of Micron Technology, unveiled its memory modules based on DDR2 SDRAM chips. The introduction further emphasizes memory makers’ desire towards transition to the new memory standard.

DDR2 (DDR-II) SDRAM 240-pin memory modules from Crucial will have 1.8V voltage and will be initially available at 400MHz (CL3) and 533MHz (CL4) speed-bins. Just like the company’s DDR products, DDR2 solutions will come in various densities, e.g. 256MB, 512MB and 1GB. The majority of DDR2 lineup from Crucial will be intended for high-end desktops, only one SKU – 512MB registered DIMM with ECC – will be intended for servers and workstations.

Later on Crucial is also expected to release 667MHz DDR2 as well as SO-DIMM DDR2 devices. Additionally, the company may broaden the range of offered DDR2 products with some other options.

Crucial Technology uses DRAMs from Micron Technology on its modules. DDR2 memory sticks are expected to feature the Boise, Idaho-based fab’s state-of-the-art BGA memory chips.

According to the news-release issued today, Crucial Technology is selling various DDR2 SDRAM memory modules on its web-site now, even though there are no mainboards with DDR2 support today. Furthermore, because DDR2 has higher latencies, initial speeds of 400MHz and 533MHz may not unleash the whole potential of the technology and systems with such modules inside may work even slower than DDR-enabled personal computers in some cases.

Crucial 256MB PC2-3200 unbuffered DIMM is currently priced at $144.99; Crucial 256MB PC2-4300 unbuffered DIMM costs $154.99; Crucial 512MB PC2-4300 is now available for $299.99; Crucial 512MB PC2-3200 registered DIMM with ECC now quoted for $344.99.
