Synopsys One-Time Programmable (OTP) NVM IP

Designers face the challenge of creating secure, cost-effective, low power, and reliable designs. Synopsys’ embedded one-time programmable (OTP) non-volatile memory (NVM) technology enables designers to address this challenge. Synopsys’ OTP NVM IP architecture provides high levels of security, high yields, low power, and excellent reliability, which is why Synopsys OTP NVM is the leader in antifuse technology with >10B units shipped and availability in more than a dozen foundries.

Synopsys OTP NVM IP is now Silicon-Proven in TSMC N5

Synopsys OTP NVM offers non-volatile storage for configuration, trimming, calibration, and encryption keys with the Base Capacity OTP product (XBC OTP), code storage with the High Capacity OTP product (XHC OTP), and secure storage with the Secure Code OTP product (XSC OTP).

Synopsys OTP NVM IP

Available in standard CMOS processes, Synopsys OTP IP does not require any additional mask layers or process steps and provides an alternative to mask ROM, eFuse and embedded Flash memory.

Synopsys OTP NVM IP addresses the power, form factor and security requirements of a broad range of applications, including code storage, encryption keys, analog trimming, and IC configuration in Power Management ICs (PMICs), Sensors, Home Entertainment, Automotive, Industrial, Mobile, Mil/Aero and IoT products.
