Micron ships world’s first 232-layer NAND chips

Matthew Wilson July 28, 2022 Featured Announcement, SSD Drives

This week Micron announced a major development in the form of the world's first 232-layer NAND. Featuring the industry-leading areal density, the new NAND delivers higher capacity and improved efficiency over previous generations.

Micron's 232-layer NAND is now in volume production, something that the company's VP of technology and products, Scott DeBoer, thinks of as a “watershed moment for storage innovation”. DeBoer goes on to add that achieving 232-layer NAND required innovation in a number of areas, from advanced process capabilities to novel materials advancements.

Micron has begun shipping its 232-layer NAND technology inside its Crucial consumer SSDs. Thanks to the ability to fit more high-speed storage chips into standard SSD form factors, we should see even higher capacity drives to cope with the growing need for mass data storage worldwide. According to Micron, the new 232-layer NAND delivers up to 100% higher bandwidth rate and more than 75% higher read bandwidth per die compared to the previous generation. We should see some new Crucial SSDs utilising the new NAND at some point too.

Micron’s 232-layer NAND is now in volume production in the company’s Singapore fab, hitting the market first via Crucial's consumer SSD product line.
