Sidense is a privately-held company that has offered one-time programmable (OTP) non-volatile memory (NVM) IP for CMOS implementation. Sidense's offering comes in sizes from 16 bits up to 1.28Mbits and complements multi-time programmable NVM IP that is already available from Synopsys, Synopsys said. The technology is deployable in 180nm down to 16nm manufacturing process technologies. Field programmable OTP NVM IP is used for fuse replacement, secure key storage, device ID, analog trim, and code storage.
The Sidense memory is based on a 1T-1antifuse technology with read access times down to 10ns. The OTP NVM 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.
