Synopsys buys fuse-based OTP memory supplier

By Nick Flaherty ay www.flaherty.co.uk

Synopsys has bought Sidense, a leading provider of one-time programmable (OTP) non-volatile memory (NVM) for automotive, mobile, industrial and Internet of Things (IoT) applications. 

The embedded one-transistor OTP technology is based on its patented split-channel 1T-Fuse bit-cell architecture that provides better yield, higher security, improved reliability and lower overall product cost. Sidense's antifuse-based OTP NVM technology offers ultra-low power, small area NVM IP with read access times as fast as 10 nanoseconds. A key advantage to Synopsys as a design tool adn IP supplier is that the IP can be manufactured in standard-logic CMOS fabrication processes and does not require any additional mask layers or process steps. The IP is in high-volume production in automotive, mobile and industrial applications.

The technology will be added to the DesignWare Multi-Time Programmable (MTP) NVM IP solution with OTP NVM IP in 16-bit to 1.28-Mbit configurations. This gives Synopsys access to proven, market-leading OTP NVM IP in process technologies from 180- to 16‑nm along with a team of highly experienced R&D engineers.

"Sidense's OTP NVM IP offers designers a secure, area-efficient solution for fuse replacement, secure key storage, device ID, analogue trim, and code storage," said Joachim Kunkel, general manager of the Solutions Group at Synopsys. "By adding OTP NVM from Sidense to our DesignWare IP portfolio, Synopsys provides designers with a broader NVM IP solution that offers small area, fast access times and high reliability for their SoC designs."
