Aplus Flash Technology announces availability of 0.35um embedded OTP EPROM IP with maximum performance: aplus' 0.35um embedded OTP IP offers high-performance , low-voltage operation on SMIC's 0.35um 2P3M OTP EPROM process

San Jose , CA, June 4, 2004 – Aplus Flash Technology has introduced an improved version of its silicon proven 0.35um 2P3M CMOS based OTP EPROM IP suitable for low voltage operations down to 1.8V. This product represents Aplus’ most advanced line of OTP EPROM IP. Aplus’ 0.5um 2P2M OTP IP has already been in stable, high-yield production at various foundries worldwide for many years.

OTP EPROM requires ultraviolet (UV) light for erasing operations. As the process technology shrinks to smaller geometries, the ability to erase uniform cells becomes more difficult. While flash memory technology has been scaled below0.13um process technology, OTP EPROM memory can not be scaled below 0.35um.

Although some companies currently offer a logic-based 0.35um OTP that uses a less mature single poly process, Aplus’ 0.35um OTP is based on a traditional double poly process. Aplus’ 2P OTP has cell size of about 10.7 ë2, while a single poly OTP process has a cell size of ~37 ë2. Single poly OTP does not have equivalent years of production data of double poly OTP. Aplus is the first company to offer 0.35um OTP EPROM IP that uses a mature, traditional, double poly CMOS process that has been silicon proven with high, stable yields and high data retention rate of over 10 years.

Embedded OTP is suitable for a wide variety of computing, communications and consumer applications. Aplus’ OTP IP can be found embedded in applications such as speech synthesis and recognition, LCD drivers, consumer appliance microcontrollers, cellular and wireless applications, and many more ASICs, DSPs and MCUs.

“Our 0.35um OTP IP offers an answer to companies looking for a low-cost flash alternative or an upgrade solution for ROM in their ICs. As the cost of OTP decreases, the benefits of having an externally programmable chip to reduce inventory becomes more attractive. We have a lot of customers asking for OTP for both of these reasons. As a proven leader in 0.5um process technology, we are happy to offer our customers the same high-quality IP in 0.35um for further cost savings. This OTP technology also provides an opportunity to many of our customers that need a cost-effective alternative to their 0.35um flash solutions,” states Dr. Henry Ma , VP of Business Development at Aplus.
