Secure Storage Solution for OTP IP

The Synopsys Secure Storage Solution for OTP is an add-on to Synopsys One-Time Programmable (OTP) Non-Volatile Memory (NVM) IP. It addresses the need for secure storage of sensitive information in embedded NVM SoCs across markets such as AI, HPC, IoT, Automotive, and Aerospace & Defense. By combining Synopsys OTP NVM IP, Synopsys SRAM PUF technology, and an industry-standard cryptographic engine, it delivers robust, hardware-based security for sensitive data, code, and keys. The SRAM PUF generates a device-specific root key at power-up, which is never stored on-chip and is used to derive keys for encrypting data stored in the OTP and scrambling addresses. This layered defense provides strong protection against attacks, keeping critical secrets secure—even if hardware is accessed directly.

The Synopsys Secure Storage Solution for OTP integrates seamlessly into SoC designs, offering flexible configuration, system-level security, and automated provisioning. It supports functions such as secure storage of keys, data, and code; ROM patching; device identification; anti-counterfeiting; and anti-rollback protection.

• OTP and Encryption Security: Address scrambling and AES encryption with SRAM PUF keys deliver secure storage for sensitive data in OTP.
• System-Level Security Extension: Optional add-on allows SRAM PUF sharing with OTP, safeguarding chip-level assets and enabling advanced key management and secure ID generation.
