Sidense Advanced Process Node 1T-OTP to Be Used in Sigma Designs DTV Products

SHF Non-Volatile Memory Macros Selected for 40nm Product Implementation

OTTAWA, ON--(Marketwired - Oct 29, 2013) - Sidense Corp., a leading developer of Logic Non-Volatile Memory (LNVM) OTP IP cores, today announced that Sigma Designs®, a leading provider of System-on-Chip (SoC) solutions for converging multimedia delivery of home entertainment, home control, and connectivity, has selected Sidense 1T-Fuse™-based 1T-OTP memory IP for use in their next generation DTV and home entertainment product lines.

Sigma Designs has signed a multi-year license to use the Sidense's SHF OTP macros. Designed by Sidense for advanced processes from 40nm down to 16nm FinFET technology, Sigma Designs will use SHF in a 40nm implementation, which has already been qualified in G and low-power/low-leakage variants, for set-top box and digital TV applications.

"Sidense secure, reliable and cost-effective embedded NVM macros are an ideal one-time programmable memory choice for our home entertainment and Digital Television products," said Jacques Martinella, Sigma Designs vice president of engineering." With products already in production using Sidense's 1T-OTP, this new license for their 40nm SHF OTP further enhances the already successful relationship we have had with Sidense since 2008."

"Working with one of the leaders in the constantly evolving consumer entertainment arena demonstrates Sidense's success in the development of its 1T-OTP products for advanced process nodes," added Xerxes Wania, CEO and president of Sidense. "The portability of our OTP macros lets customers such as Sigma Designs choose the best Sidense OTP product and implementation path for their silicon."

About SHF
Sidense SHF One-Time Programmable (OTP) memory IP is based on a patented 1T-Fuse™ (antifuse) bit-cell. The 1T-Fuse bit-cell uses gate oxide breakdown as a robust, non-reversible programming mechanism. Optimized for high-performance and a wide range of bit densities, Sidense SHF macros are available for standard CMOS processes with no requirements for any additional masks or processing steps.

Sidense SHF memory IP is provided as a complete, non-volatile memory subsystem providing interfaces and features to support a range of embedded SoC applications. The SHF module integrates the OTP memory and Integrated Power Supply (IPS) hard macro blocks along with program control, programming and test interface, error correction and Built-In Self -Test (BIST) RTL. SHF applications include: code storage, ROM replacement, secure encryption key storage, configuration, fuse replacement, trimming and calibration.

About Sidense Corp.
Sidense Corp. provides very dense, highly reliable and secure non-volatile one-time programmable (OTP) Logic Non-Volatile Memory (LNVM) IP for use in standard-logic CMOS processes. The Company, with over 115 patents granted or pending, licenses OTP memory IP based on its innovative one-transistor 1T-Fuse™ bit cell, which does not require extra masks or process steps to manufacture. Sidense 1T-OTP macros provide a better field-programmable, reliable and cost-effective solution than flash, mask ROM, eFuse and other embedded and off-chip NVM technologies for many code storage, encryption key, analog trimming and device configuration uses.

Over 110 companies, including many of the top fabless semiconductor manufacturers and IDMs, have adopted Sidense 1T-OTP as their NVM solution for more than 350 designs. Customers are realizing outstanding savings in solution cost and power consumption along with better security and reliability for applications ranging from mobile and consumer devices to high-temperature, high-reliability automotive and industrial electronics. The IP is offered at and supported by all top-tier semiconductor foundries and selected IDMs. Sidense is headquartered in Ottawa, Canada with sales offices worldwide.
