Resistive RAM (ReRAM) technology has been waiting for its moment in the sun for several years now. Despite its placement on the roadmaps of several chip manufacturers and as part of novel architectures like HPE's shuttered memristor-based "The Machine" project, it never took off as a revolutionary memory technology, even though the concept makes excellent sense.
Manufacturability, cost, and other factors played a role but for companies like Crossbar, which staked an entire business on the emerging role of ReRAM, the gambit has yet to pay off. That same company today announced a possible new life for ReRAM technology–in security.
CrossBar, Inc. says ReRAM technology can be used in the creation of physical unclonable function (PUF) cryptographic keys since each key is specific to the individual IC.
