Intel and Micron jolted the NAND flash race in July 2006 by announcing that their IM Flash Technologies venture was sampling 4 Gb NAND devices made on a 50 nm process. They planned to mass-produce a range of densities on that node in 2007—but the announcement established a sampling milestone and a production plan, not that mass production had begun.
What Intel and Micron announced in July 2006
On July 25, Intel and Micron said IM Flash Technologies was sampling 4 Gb NAND flash devices fabricated at 50 nm. The partners said they intended to mass-produce a range of densities using the process in 2007. The distinction matters: the release documents samples and an intention, not a confirmed production start date or shipment volume. Intel and Micron’s announcement called the devices the companies’ first 50 nm NAND samples.
At the time, EE Times characterized the move as a surprise and a process-technology leapfrog. That captures the news value of the announcement, but does not establish that Intel and Micron led on every measure of NAND competitiveness.
How the milestones compare
These announcements came at different times and described different device densities and stages. “Sampling,” “commercial samples available,” “planned production,” and “mass production” are not interchangeable milestones.

- Reduce pin count and increase efficiency with the W25Q128 NOR Flash Memory Chip Module. The W25Q series provides fewer pin packages compared to parallel flashing, making it a more efficient and compact solution for your data storage needs
- Achieve double the operating frequency with the W25Q128 NOR Flash Memory Chip Module, supporting dual SPI dual input mode. With an operating frequency of 104MHz, it delivers four times the operating efficiency, making it ideal for high-speed and reliable data storage
| Company or partnership | Node label | Device density | Milestone described |
|---|---|---|---|
| IM Flash Technologies (Intel and Micron) | 50 nm | 4 Gb | Sampling announced July 25, 2006; mass production of a range of densities planned for 2007. The release does not confirm when production began. Intel and Micron |
| Toshiba and SanDisk | 56 nm | 8 Gb and 16 Gb | Toshiba said commercial samples of the 8 Gb device were available in January 2007; samples of the 16 Gb device were planned for later that quarter. Toshiba |
| Samsung | 51 nm | 16 Gb | Samsung announced on April 28, 2007, that mass production had begun. Samsung Semiconductor |
On those specific milestones, Intel and Micron were first among the announcements covered here to report sampling a 50 nm NAND device. That is a narrower and better-supported claim than saying they “won” the NAND race. Toshiba’s 56 nm products had higher stated densities, while Samsung’s later 51 nm announcement described mass production; neither comparison erases the difference in dates, node labels, densities, and stages.
What Samsung’s timeline adds
Samsung’s own retrospective lists its NAND process milestones as 90 nm in 2002, 70 nm in 2003, 50 nm in 2005, 40 nm in 2006, and 30 nm in 2007. This is the company’s account of its development history; it does not independently establish a cross-company ranking. Samsung’s milestone timeline should also be read alongside its separate report of 51 nm, 16 Gb mass production in April 2007.

Samsung said its 51 nm chips could be produced 60 percent more efficiently than its 60 nm devices. That is Samsung’s comparison in its announcement, not an independently verified industry-wide measurement. The same release quotes flash-marketing director Jim Elliott: “To minimize production costs and improve performance, we have applied the finest process technology a ”half generation” ahead of the industry, which is introducing 55nm and higher.” The statement is a company marketing claim, not an independent assessment.

Why the 50 nm milestone was not the end of NAND scaling
Process shrink was only one route to increasing NAND capacity. In June 2007, Toshiba announced a 32-layer stacked NAND structure and said it could deliver ten times the integration of a standard chip made with the same generation of technology. That was a different architectural approach from simply comparing planar process-node labels. Toshiba’s 2007 announcement

Samsung says it began mass production of 3D V-NAND in 2013. These examples show the later use of vertical structures, but they do not establish one precise date when planar NAND scaling ended. Samsung’s company history

The phrase describes how Intel and Micron’s 50 nm sampling announcement altered the competitive story in 2006. It does not prove an overall victory based on yield, cost, reliability, shipment volume, performance, or market share. The defensible takeaway is milestone-specific: Intel and Micron announced 4 Gb samples at 50 nm; Toshiba and SanDisk later announced 56 nm 8 Gb and 16 Gb products at different sampling stages; and Samsung subsequently announced mass production of 16 Gb devices at 51 nm.
