Sidense's SiPROM OTP IP is based on a patented, area-efficient antifuse cell – 1T Fuse(TM) – employing controlled gate oxide breakdown as a programming mechanism. Available in a standard CMOS process, Sidense macrocells do not require any additional mask layers or process steps and provide an alternative to mask ROM, eFuses and Flash memory in many applications.
The reduced size of the single transistor bit-cell results in better yield, higher security, improved reliability and lower overall product cost.
SiPROM products are silicon proven and are available at all top-tier foundries and selected IDMs. The IP is available in standard-logic CMOS processes at 130nm, 110nm, 90nm, 65nm, and 55nm and is scalable to 28nm and below.
