Overview
Data protection from safeguarded anti-fuse OTP memory
Secure OTP is a combined Physical Macro, and Digital RTL providing comprehensive data protection. It is the ultimate solution for embedded Non-Volatile Memory in CMOS logic or logic-derived technologies. The RTL part provides glue logic of the OTP/PUF controller, tamperproof features, and standard AMBA interfacing. Secure OTPs tailored design maximizes efficiency and allows simplified integration across multiple emerging IC markets and ASIC applications. It is available in various densities and configurations with several CMOS technologies, delivering an embedded non-volatile memory with outstanding reliability and performance.
Secure OTP includes a 1024-bit Physical Unclonable Function (PUF), which is used for physical address scrambling and IO shuffling to enhance stored data security. It is a pure hardware PUF with a virtually ideal entropy that doesn’t require any helper data for error correction, allowing access within a few microseconds.
Secure OTP leads the field in terms of enhanced security OTP platform availability. Through PUFsecurity’s parent company, eMemory, we draw from over 20 years of experience partnering with foundries and delivering high-quality IPs.
Today, the rising security risks to IoT devices are limiting the market’s potential. The answer is creating a collaborative security ecosystem that draws from the safest Hardware, Software, and Operating System solutions. Secure OTP can become the bedrock of any chip security ecosystem and protect critical data such as the root key and the boot code.

The hardware root of trust (HRoT) provides the trust base (root key), hardware identifier (UID), hardware unique key (HUK), and entropy required for the secure operation of the entire chip and therefore is often the focus of hacker attacks. If the design can’t effectively resist attacks, hackers can easily obtain the secrets of the entire chip. Attackers can use the secrets to crack identity authentication and data encryption and steal product design know-how, causing application security problems.
A sensor is a device that detects a change in a stimulus and converts it into an electronic signal that can be measured or recorded. The stimulus can be many things, including a physical property, environmental parameter, chemical composition or a location, to name just a few. All sensing elements have nonlinearities that include an intrinsic nonlinearity over sensing range along with offset and sensitivity nonlinearity variations over temperature.
With the invention of Physical Unclonable Functions (PUF), we can now create a unique, inborn, unclonable key at the hardware level. The natural follow-up question to this is, “but how do we protect this key?” It is like storing your key to secrets in a drawer, a surefire way to break the secure boundary and create vulnerabilities.
The market for piracy is huge and hackers have become increasingly sophisticated even when security is implemented in hardware. The race between the aggressors and protectors is a battle without end. Smart connected home devices are increasingly storing and processing very sensitive and private user data in addition to attempting to deliver copyright protected content from service providers. Protecting consumer data is vital.
While leading foundries keep pushing Moore’s law to the limit of physics, embedded non-volatile memory (eNVM) is becoming a game-changer in designing advanced integrated chips.
Patented by Attopsemi™, I-fuse™ is a revolutionary non-breaking fuse technology that can be reliably programmed by heat assisted electromigration below a break point. Any cell can be tested as programmable if the initial fuse resistance is low enough (e.g. <400 ohms) to generate enough heat for programming.
