The connected world we live in today depends on billions of chips. The sheer volume of chips required for a functioning society is staggering. But what is equally remarkable is the technology that secures them.

Without robust security, even the most sophisticated chips would be unable to fulfill their purpose. Data would be at constant risk, trust would be nonexistent, and regulatory compliance would be impossible. Static Random-Access Memory Physical Unclonable Function (SRAM PUF) technology is a vital asset in the fight against the cyber threats that are an ever-present reality, helping to protect both individual devices and interconnected systems.

To understand how SRAM PUF works, let’s first define what a PUF is. In the simplest terms, it is something that provides a physically defined digital fingerprint that acts as a unique identifier. Its most common application is for semiconductor devices such as microprocessors.
