Mobile 3D NAND Flash Memory for Smartphones

Micron Announces Leading-Edge, Mobile 3D NAND Flash Solutions for Flagship Smartphones

Micron Technology, Inc.BARCELONA, Spain, Feb. 26, 2018 (GLOBE NEWSWIRE) — Micron Technology, Inc. (Nasdaq:MU) announced today three new 64-layer, second-generation 3D NAND Flash storage products, which support the high-speed Universal Flash Storage (UFS) 2.1 standard. Micron’s new mobile 3D NAND products are available in 256GB, 128GB and 64GB capacities.

These new mobile solutions are based on Micron’s industry-leading triple level cell (TLC) 3D NAND technology, empowering smartphone makers to enhance the user experience with next-generation mobile features such as artificial intelligence (AI), virtual reality and facial recognition. The emergence of AI in flagship phones is driving the need for more advanced storage solutions that enable faster and more efficient access to data. Analyst firm Gartner predicts that by 2022, 80 percent of all smartphones will have on-device AI capabilities, increasing the requirement to process and store more data locally.1

Additionally, storage capacity has continued to increase significantly as smartphones have become the go-to devices for photography and multimedia sharing, with up to 256GB in flagship phones today and projections for that to grow to a terabyte by 2021. Micron’s new 64-layer TLC 3D NAND storage solutions address these needs by utilizing a mobile-optimized architecture to deliver consistent high performance and low latency, while offering more capacity in a smaller space.

“Memory plays an increasingly critical role in delivering the bold new features we have all come to expect from our smartphones,” said Gino Skulick, Micron vice president of marketing, Mobile Business Unit. “Micron uniquely delivers both mobile DRAM and 3D NAND, and our leading-edge designs continue to provide the performance demanded by the most advanced smartphones.”

The new mobile 3D NAND flash products pack more storage cells into a smaller die area, and by utilizing Micron’s CMOS under Array (CuA), they deliver a best-in-class die size. Micron’s unique approach places all the flash memory layers on top of the logic array, maximizing the use of space in the smartphone design.

Micron’s second-generation TLC 3D NAND flash for mobile offers several competitive technical advantages, including the new features described below:

  • Micron‘s mobile-optimized architecture delivers consistent high performance and low latency for an enhanced user experience, while minimizing power consumption through the use of an efficient peak power management system.
  • Micron’s new 64-layer TLC 3D NAND products are 50 percent faster than previous-generation TLC 3D NAND.
  • Micron’s 64-layer 3D NAND Flash technology doubles the storage density of previous-generation TLC 3D NAND while maintaining the same package size.
  • The UFS 2.1 G3-2L interface specification provides compelling performance for mobile applications, delivering up to 200 percent higher bandwidth versus e.MMC 5.1 and providing simultaneous read and write capabilities. This underpins the speed of data access needed when capturing bursts of high-resolution photos or recording 4K video to storage.
  • The new products are based on a 32GB die, which measures 59.341mm2 — the industry’s smallest 32GB TLC 3D NAND die on the market.2
