eMemory's Security-Enhanced OTP Qualifies on TSMC N5A Process Specializing in High-Performance Automotive Chips

Hsinchu Taiwan -- July 3, 2024 -- eMemory’s security-enhanced version of NeoFuse OTP has qualified for the TSMC N5A platform - an enhanced process for automotive applications. With the rising demands for autonomous driving and electric vehicles, automotive chips must possess high-computing capabilities while adhering to strict safety standards. The N5A technology brings the same technology used in supercomputers today to vehicles, packing the performance, power efficiency, and logic density of N5 while meeting the stringent quality and reliability requirements of automotive safety and quality standards.

NeoFuse OTP on the TSMC N5A process features the versatility to support applications requiring either high performance or low power consumption, along with the added benefit of heightened security. The security-enhanced OTP macro includes eMemory’s proprietary physical unclonable function (PUF) to anchor the IC’s root of trust into the silicon. The memory array is designed with wide bandwidth output, allowing customers to utilize additional IO for the ECC function, which further boosts reliability for auto applications. The IP also boasts complete design simulation, including Electromigration/Aging, and adheres to additional design rules for the N5A process. At the operational level, the temperature tolerance extends up to 150°C, and the wide voltage range offers greater flexibility to meet diverse automotive application requirements and stringent standards. As a long-standing market-leading advantage, eMemory’s OTP does not require extra masks on the N5A process, thus significantly reducing costs.

"Nowadays, consumers’ high expectations for driving experiences have resulted in a significant increase of electronics presented in a car, whether for self-driving, upgraded infotainment, or EVs. Many ICs need high-performance computing with maximum security to meet these requirements. eMemory’s NeoFuse OTP on the N5A process addresses such demands while meeting safety standards, such as AEC Q-100. We are happy to note that there are customers waiting for our solutions. Moving forward, we will continue to provide reliable IPs with exceptional services to the ever-revolutionizing industry," said Chris Lu, Senior Vice President of Business Development of eMemory.
