HP Makes Progress on Revolutionary Memristors
“Our brains are made of memristors,” he said, referring to the function of biological synapses. “We have the right stuff now to build real brains.”
In an interview at the H.P. research lab, Stan Williams, a company physicist, said that in the two years since announcing working devices, his team had increased their switching speed to match today’s conventional silicon transistors. The researchers had tested them in the laboratory, he added, proving they could reliably make hundreds of thousands of reads and writes.
That is a significant hurdle to overcome, indicating that it is now possible to consider memristor-based chips as an alternative to today’s transistor-based flash computer memories, which are widely used in consumer devices like MP3 players, portable computers and digital cameras.
“Not only do we think that in three years we can be better than the competitors,” Dr. Williams said. “The memristor technology really has the capacity to continue scaling for a very long time, and that’s really a big deal.”
