Intel Corp. and Micron Technology said they had begin sampling of flash memory chips manufactured using 50nm process technology. The samples were manufactured through IM Flash Technologies, a joint development and manufacturing venture from Micron and Intel.

Both companies sample 4Gb memory devices, but they expect to produce various models of NAND flash memory chips at so far the world’s thinnest 50nm process technology in 2007. No information about the devices is known, however, it is likely that the devices may employ the so-called open NAND flash interface (ONFI) proposed in May, 2006.

This move to 50nm process technology will enable Intel and Micron to meet the growing demand for higher density NAND flash across a range of computing and consumer electronics applications such as digital music players, removable storage and handheld communications devices. According to industry research forecasts, the NAND market segment is estimated to reach $13 to $16 billion in 2006 and grow to approximately $25 to $30 billion by 2010.

Micron and Intel formed IM Flash Technologies (IMFT) in January to manufacture NAND flash memory products for the two companies. Micron is currently supplying the venture NAND flash from its Boise fabrication facilities, and Micron’s 300 mm facility in Manassas, Virginia, will be online later this year to supply IMFT with NAND. Meanwhile, the Lehi, Utah facility that is dedicated to IMFT and serves as its headquarters is expected to be online producing NAND early next year.
