Light-Based Memory Chip

First Light-Based Memory Chip Puts SSDs on Notice

Steve Dent | September 28, 2015


Researchers have created the first optical-only chip that can permanently store data, a discovery that could lead to storage devices that leave SSDs in the dust. Non-volatile flash memory currently relies on electronic chips, which are speed-limited by the heat and resistance generated by colliding electrons. Light-based circuits don't have that problem, but so far "nano-photonic" chips created by the likes of IBM are volatile (need to be powered), making them a non-option for permanent storage.
