Manufacturing Company TSMC has introduced an 0.25µ flash
cell to its family of patented embedded flash technologies, or EmbFlash™.
TSMC is one of the few manufacturers of
cost-efficient program memory Flash cells that pass most vendor quality
standards. Presently, TSMC has embedded flash cells in geometries of 0.5µ
and 0.35µ that are used by microcontroller manufacturers such as
Motorola, National Semiconductor, and Scenix.
The use of embedded flash has been gaining in
popularity in recent years. On-chip flash provides several advantages in
microcontroller-based systems:
- In-System programmability allows for the microcontroller
to be programmed in the field without having to change components.
- Significant space is saved by reducing the number
of external components
- Component reduction adds to the reliability of
most systems.
- In some systems, reduced power consumption may be
evidenced.
According to TSMC, 0.25um EmbFlash™ is ideal for applications requiring
high-density flash, particularly, wireless data devices such as cellular
phones and PDAs. TSMC provides the Flash IP (FlashIP™) and SRAM
IP in support of flash densities up to 32Mb and SRAM densities up to 4Mb,
thereby increasing design flexibility and accelerate time-to-market for
customers' designs.
Wireless designs, especially those in the cellular market, often employ multi-chip module (MCM) solutions that integrate separate
microcontroller and flash dies in a single package. While MCMs may achieve
design density, MCMs are highly susceptible to temperature extremes and
also can generate excess EMI. Microcontrollers with flash on-chip provide a superior alternative for vendors to differentiate their
products in performance, features, and temperature
stability.
"Compared to the MCM solutions used in the cellular phone, the
EmbFlash™ solution can further improve the power, performance, and
even cost," said Sam Chu, the director of Embedded
Non-Volatile Memory at TSMC. "Our
FlashIP™ set features combined density, configuration, and
performance improvements that simply aren't available from stand-alone
memory. In addition, the design and test support from TSMC enables our
customers to integrate flash and SRAM with greater ease and minimum
overhead."
Availability
TSMC is presently accepting customer tape-outs for its
0.25µ embedded flash process. The company is also pursuing a next-generation,
0.18-micron EmbFlash™ technology, which is scheduled for release
late 2000.
About TSMC
TSMC is the world's largest dedicated semiconductor foundry, providing the
industry's leading process technology, library and IP options and other
leading-edge foundry services. TSMC operates five eight-inch wafer fabs
(Fab 3, 4, 5, TASMC and WaferTech), and two six-inch wafer fabs (Fabs 1
and 2). In addition, the company is ramping Fab 6, located in Tainan Taiwan,
for production and has begun construction of a $1.2 billion joint venture fab
with Philips Semiconductor, which is scheduled to open in Singapore in
2000. TSMC has broken ground for a new 12-inch wafer fabrication facility in
Hsin-Chu and will soon break ground for fab 7 in Tainan, which will be the
company's sixth eight-inch fab. In year 2000, TSMC will have the capacity for
nearly 3 million 8-inch equivalent wafers. Fabrication processes offered by
TSMC include CMOS logic, mixed-mode, volatile and non-volatile memory,
and BiCMOS. TSMC's corporate headquarters are in Hsin-Chu, Taiwan.
