Kilopass’ TSMC 28nm HKMG Silicon Results Show Scalability of 2T Antifuse Technology

Santa Clara, Calif. –– April 5, 2011 –– Kilopass Technology Inc., a leading provider of semiconductor logic non-volatile memory (NVM) intellectual property (IP), today announced that its first test chip silicon on TSMC 28nm High-K Metal Gate (HKMG) has demonstrated that Kilopass’ 2T antifuse technology is scalable to HKMG.  Silicon data shows that existing 2T bit cell performs well on 28HKMG and can scale to 22nm and beyond. This milestone demonstrates how Kilopass patented antifuse NVM technology can migrate to bleeding edge logic CMOS processes.

“We are extremely pleased with the 2T antifuse silicon results on TSMC 28nm HKMG process,” said Harry Luan, CTO at Kilopass.  “The testchip silicon contained a variety of 2T bit cell for fundamental device study and cell modeling. Silicon results show that Kilopass’ 2T technology in HKMG has excellent programming distribution and no program disturb behavior is observed. In addition, the gate leakage is significantly reduced from previous process generations which will contribute to a better read margin and high incoming yield.”

Kilopass embedded NVM is implemented in standard CMOS without any additional backend process steps. It is designed for manufacturability for mass production; it follows foundry DFM design rules, utilizes standard devices supplied by the foundry, and requires no additional overlay tolerance or process control. Over two billion integrated circuits with Kilopass 2T antifuse technology from 0.18um to 40nm have shipped in consumer, automotive, mobile, and analog mixed signal products.  At 28nm HKMG, silicon results show Kilopass embedded NVM technology will continue to be implemented in standard CMOS and scale in area and power with the 28nm HKMG process.

Product Availability

Kilopass XPM™ and Gusto™ memory IP for TSMC 28nm HKMG process will be available for licensing in second half of 2011.  Kilopass has begun providing advanced information to customers with designs targeting the 28nm HKMG process.

Power Multiplexing with Discrete Components

Sponsored by Mouser Electronics and Toshiba

Power multiplexing is a vital design requirement for a variety of different applications today. In this episode of Chalk Talk, Amelia Dalton chats with Talayeh Saderi from Toshiba about what kind of power multiplex solution would be the best fit for your next design. They discuss five unique design considerations that we should think about when it comes to power multiplexing and the benefits that high side gate drivers bring to power multiplexing.
