SST, TSMC to jointly develop 90nm SuperFlash

Companies plan to be the first on the market with licensable 90nm embedded flash technology

Taiwan Semiconductor Manufacturing Co. (TSMC) and Silicon Storage Technology (SST) have agreed to work together on developing 90-nanometer embedded SuperFlash technology, with TSMC to license the technology as part of its portfolio, the companies announced on Monday.

The companies plan to be the first on the market to offer the licensable 90nm embedded flash technology.

The 90nm SuperFlash technology is designed for use by high density applications that require low power and could be used in 64-bit MCU (microcontroller) cores, high-speed ASICs (application-specific integrated circuits) and multimedia ICs (integrated circuits).

A nanometer is a billionth of a meter and a 90-nanometer chip is one in which the smallest feature on it is 90nm in size.

Chip makers are racing to make ever smaller features and while many of today’s chips use 90nm and 65nm technology, developers are working on 45nm production.

Demand for embedded 90nm flash technology will come from the continuing growth of consumer and mobile electronics devices, which increasingly require more advanced embedded flash technologies as they begin to include more functionality, according to Web-Feet Research.

SuperFlash, which is proprietary technology developed by SST, is used in various flash memory components and flash mass storage products.

The development of the 90-nanometer SuperFlash technology is part of SST’s strategy of scaling the technology to finer process geometries, the company said.

Samples of the product will become available next year.
