Micron starts producing 34nm NAND flash chips

— 5:04 PM on June 30, 2009

Solid-state drives aren't the only devices to benefit from advancements in flash technology—more pedestrian products like memory cards do, too. Speaking of which, Micron says it's started mass-producing a pair of multi-level cell NAND flash chips based on its new (and purportedly "award-winning") 34nm process technology.

The chips have capacities of 16Gb and 32Gb, or 2GB and 4GB, and they both have an ONFI 2.1 interface that allows transfer speeds as high as 200MB/s. That interface supposedly delivers the "fastest read and write throughputs offered in today's NAND devices," and it will find its way in "all future high-density Micron NAND products."

Since the chips are so tiny—Micron quotes 84 mm² for the 2GB model pictured above—they should find their way into memory cards with pretty high capacities. Already, Micron says Lexar is using them in 32GB Secure Digital High Capacity memory cards with a 60X speed rating. According to Micron, the cards offer minimum sustained transfer rates of 12MB/s for reads and 9MB/s for writes.

Lexar also intends to use Micron's new 34nm NAND chips in microSDHC, SD, Compact Flash, and Memory Stick Pro Duo devices, not to mention a number of USB flash drives. The announcement doesn't say anything about SSDs, though.
