The company received the honor at the flagship conference of the IEEE Solid-State Circuits Society February 18th in San Francisco for its paper “A PUF Scheme Using Competing Oxide Rupture with Bit Error Rate Approaching Zero”.

The paper, featuring eMemory’s patented security technology NeoPUF, was highly rated by attendees of the ISSCC, for its breakthrough in overcoming reliability issues common to conventional PUF (Physically Unclonable Functions) technologies.

While PUF is increasingly used in security applications, the conventional technologies are by nature sensitive to environmental conditions, such as temperature, voltage, and noise. As a result, they require not only ECC but also complicated pre/post-processing to generate stable PUF output as the root of random source.

eMemory’s NeoPUF, on the other hand, is able to produce reliable and uniformly distributed random PUF output without the need for complex error correction or helper data. The IP, verified for the 7nm technology, has been designed in by customers.

“eMemory has long been dedicated to developments of core technologies in line with latest trends in the marketplace, “ said Rick Shen, president of the eMemory. “The (Takuo Sugano) Award recognizes that our team is capable of developing technologies that are commercially applicable as well as successful from the academic point of view.”

The NeoPUF technology, derived from the standard CMOS logic process, generates a silicon fingerprint on individual ICs, which can be used as an entropy source or a root of trust in security applications.

An embedded NeoPUF scheme can secure the chip and the hardware from the first point of the manufacturing process to their implementation and long-term operation, ideal for security-sensitive applications including AIoT(AI+IoT) and automotive.

A NeoPUF macro, comprised of eMemory’s patented cell array architecture and verified security circuitry, can generate an entropy source up to 64K bits.

The PUF outputs are consistent without bit errors at an extended temperature range from -40°C to +150°C. The zero bit error rate eliminates the need for complicated error correction measures.

The NeoPUF solution also includes IP blocks of key provisioning, crypto engine, and tamper protections, providing a holistic protection for hardware.
