HP Labs
Hewlett-Packard's central research lab in Palo Alto — birthplace of PA-RISC, the idea behind Itanium, and the most talked-about memristor never to ship.
Bill Hewlett and David Packard set up the lab in 1966 to do research that didn't belong to any single product division. In the 1980s Joel Birnbaum led the work that became PA-RISC, and in the early 1990s Bob Rau and Josh Fisher developed the VLIW ideas HP carried into its 1994 partnership with Intel — the one that produced Itanium.
In 2008 Stan Williams' group published a Nature paper on a working memristor, the fourth passive circuit element theory had predicted since 1971. It was meant to anchor The Machine, a computer built around one vast pool of memory. The prototype was shown in 2017; the memristors were not in it. When the company split in 2015 the lab went to HP Inc, while Hewlett Packard Enterprise built up research of its own.
