Micron Technology 232-Layer NAND
Micron Technology announced today that the company has begun volume production of the world’s first 232-layer NAND, which enables the introduction of the industry’s fastest NAND I/O speed ‒ 2.4 gigabytes per second (GB/s). To put that in comparison, this speed represents a 50% faster data transfer than the fastest interface enabled on Micron’s 176-layer node.

The 232-layer NAND also debuts the world’s first six-plane TLC production NAND, the most planes per die of any TLC flash. It features independent read capability in each plane. while the structure itself ensures fewer collisions between write and read commands as well as offers drives system-level quality-of-service improvements. Thanks to NV-LPDDR4 support, a low-voltage interface, 232-layer NAND solutions offer ideal support for mobile applications and deployments in the data center. With volume production ramping up, we expect to see drives using this technology in the next few months. We’re still waiting for graphene-based hard disk drives to hit the market since they can hold up to 10-times more than a traditional drive.

  • Get NVMe solid state performance featuring up to 1050MB/s read and up to 1000MB/s write speeds in a portable, high-capacity drive that’s perfect for creating amazing content or capturing incredible footage. (Requires compatible devices capable of reaching such speed. Based on internal testing; performance may be lower depending on host device, interface, usage conditions and other factors. 1MB=1,000,000 bytes.)
  • Up to 2-meter drop protection and IP55 water and dust resistance mean this tough drive can take a beating.
  • Use the handy carabiner loop to secure it to your belt loop or backpack for extra peace of mind.
  • Help keep private content private with the included password protection featuring 256‐bit AES hardware encryption.

Micron’s 232-layer NAND is a watershed moment for storage innovation as first proof of the capability to scale 3D NAND to more than 200 layers in production. This groundbreaking technology required extensive innovation, including advanced process capabilities to create high aspect ratio structures, novel materials advancements and leading-edge design enhancements that build on our market-leading 176-layer NAND technology,” said Scott DeBoer, executive vice president of technology and products at Micron.
