Optical Memory Chip Uses Phase-Change Material

Facebook X LinkedIn Email
The first demonstration of a stable nanoscale optical memory chip could allow storage and retrieval of data without the latency inherent in electronic systems. The prototype, developed by researchers in Germany and England, incorporates phase-change materials onto which data can be encoded and erased using ultrashort light pulses. "Optical bits can be written in our system at frequencies of up to a gigahertz or more," said Oxford University professor Harish Bhaskaran, "and our approach can define a new speed limit for future processors, by delivering extremely fast on-chip optical...Read full article
