eMemory's Security-Enhanced OTP Qualifies on TSMC N4P Process, Pushing Forward in High-Performance Leading Technology

Hsinchu Taiwan -- January 25, 2024 -- eMemory announced that its security-enhanced version of One-Time Programmable (OTP), NeoFuse, has achieved qualification on the TSMC N4P process. As a performance-focused enhancement of TSMC’s 5nm family, N4P was optimized to provide a further enhanced advanced technology platform for both HPC and mobile applications. In addition, N4P lowers process complexity and improves wafer cycle time by reducing the number of masks. As NeoFuse is fully compatible with the N4P process, no additional masks are required.

NeoFuse OTP on the TSMC N4P process is an embedded one-time programmable NVM IP solution, featuring low operating power, robust reliability, and heightened security. The security-enhanced OTP macro incorporates eMemory’s proprietary physical unclonable function (PUF). The PUF feature provides additional value of data protection and anchors the IC’s root of trust into the silicon. At the operational level, the temperature tolerance extends up to 150°C, covering a wider range of supply voltages.

"Along with TSMC’s outstanding semiconductor manufacturing capabilities, eMemory’s new milestone on the N4P process ushers in more powerful and flexible NVM and security solutions for HPC, AI, Cloud Server, and mobile applications. Our goal is to lead the innovation of NVM technology and serve our mutual customers in this rapid-evolving era," said Chris Lu, Senior Vice President of Business Development of eMemory.

“Our latest collaboration with eMemory provides customers with qualified design solutions that allow them to fully leverage the significant performance boost of TSMC’s advanced process technologies,” said Dan Kochpatcharin, head of the Design Infrastructure Management Division at TSMC. “We will continue to work closely with our Open Innovation Platform^® (OIP) ecosystem partners to help customers address the stringent design challenges and unleash next-generation HPC and mobile innovations.”

eMemory expects to complete qualification on the TSMC N5A process for automotive applications by the first quarter of 2024. The N3P project is currently under development and is scheduled to tape out in the first quarter of 2024.

Through close collaboration with TSMC in design solution development for advanced process technologies, eMemory remains committed to the best security-enhanced OTP and security solutions for various application trends, including smartphones, HPC, mobile, AI, automotive, and Cloud server.
