At the scale of the Vera Rubin platform, yield, calibration, and security failures compound across tens of thousands of devices. A single unified hardware anchor at the silicon level is not optional, it is architectural necessity. A physical unclonable function-based hardware root-of-trust, PUFrt, jointly developed by eMemory and PUFsecurity, was designed precisely for this role: a fully integrated implementation of the Caliptra 2.0 open standard that simultaneously manages cross-die memory repair and hardware root of trust across the full platform.
This article provides an in-depth analysis of the specific PPA challenges introduced by PQC and elucidates how PUF-PQC leverages its unique dualtrack strategy to deliver a robust and flexible Hardware Root of Trust (HRoT) across diverse application scenarios. Furthermore, it demonstrates the integration of Physical Unclonable Function (PUF) with a NIST SP 800-90B compliant True Random Number Generator (TRNG) to serve as critical components of PUFrt (Root of Trust), ensuring the security of post-quantum key generation starting from the entropy source.
eMemory won this year’s OIP award in the category of Specialty Embedded Memory IP for its commitment to IP innovation, technical support for TSMC, and service that adapts to the changing needs of global semiconductor customers.
By integrating PUFsecurity’s Physically Unclonable Function (PUF)-based hardware root of trust with Carota’s proven OTA platform, the companies will deliver end-to-end, hardware-anchored cybersecurity for the next generation of connected vehicles and AIoT, and the broader Software-Defined Anything (SDx) ecosystem.
NeoFuse OTP on TSMC’s N3P process delivers outstanding performance with support for up to 4Kx40 bits density and a wide operating voltage range from 0.55V to 0.96V. These capabilities enable high-capacity data storage and reliable system design, essential for AI SoCs, HPC processors, automotive electronics, and other applications requiring high-density embedded memory.
This groundbreaking innovation combines eMemory’s cutting-edge NeoPUF technology with advanced PQC algorithms to deliver unparalleled security for the next generation of computing, safeguarding devices against the emerging threats posed by quantum computing.
