Sigma Designs Employs Sidense Memory in IPTV Product

  • Ease of process and foundry portability a key factor in choosing Sidense OTP macros
Ottawa, Canada - January 6th, 2009 - Sidense, a leading developer of Logic Non-Volatile Memory (LNVM) IP cores, today announced that Sigma Designs (NASDAQ: SIGM), a leader in digital media processor SoCs for consumer electronics, has selected Sidense’s one-time programmable (OTP) memory IP for their future chipset products. Sidense’s flexible SiPROM architecture allows Sigma to securely embed HDCP keys as well as boot code in their next-generation internet protocol television (IPTV) SoCs.

“We designed our 1T-Fuse OTP architecture to minimize implementation effort when porting chips between foundries or to advanced process nodes,” said Xerxes Wania, President and CEO of Sidense. “This provides our customers with a high level of foundry and process node flexibility, resulting in faster time to market and cost reduction when changing processes.”

Sigma’s media processors integrate a wide complement of advanced capabilities for a system-on-chip (SoC) solution with powerful multimedia processing, a robust content security system, multiple on-chip CPUs, and a range of on-chip system peripherals. Sigma’s upcoming range of SoCs will feature on-chip OTP memory to provide increased security and configurability for future set-top box oriented solutions.

“Selling to the consumer market, it is essential for us to have the flexibility to offer a variety of on-chip content security options while being able to change nodes and processes at our discretion,” said Ken Lowe, vice president of strategic marketing. “We found that Sidense was the only NVM provider that had such a wide range of foundry and advanced node coverage.”
