Sidense Corp., founded in 2004, is a leading developer of silicon-proven embedded non-volatile memory (NVM) intellectual property (IP). Sidense's patented one-time programmable (OTP) memory enables a wide range of electronic products which are based upon complex System on Chip (SOC) semiconductors. End-market products include home entertainment consumer products, cellular telephones, RFID, medical, automotive and a host of other uses.

Semiconductor and systems companies integrate Sidense IP cores into their SOC designs, saving time and money and allowing them to focus on the core competencies that differentiate their products. Sidense provides IP which is difficult and uneconomical for the device makers to try to create on their own.

Important requirements of Sidense customers include the need to incorporate NVM that can be manufactured on a standard-logic CMOS process, has very small area footprints, very fast read access times, the inability to be reverse engineered, and very low operating power consumption. Sidense is the only supplier of NVM IP that can meet all of these demanding requirements.

Sidense IP is available from many popular top-tier foundries from 180nm to 20nm.
