ReRAMs can be used as PUFs

While historically utilized as non-volatile semiconductor memory, CrossBar’s ReRAM technology in now being introduced for use in hardware security applications utilising its ReRAM based cryptographic PUF keys, enabling a more secure and cost-effective class of devices and systems.


“We believe the state-of-the-art use of our unique technology as PUF cryptographic keys will provide higher security for our customers’ products,” says CEO Mark Davis,

To resist cyber attacks, devices are integrating secret cryptographic “keys” to facilitate secure communications and control.  While there are numerous technologies currently utilized as PUF keys, the most common approach leverages semiconductor SRAM.
