Setting a new benchmark for Flash memory performance, a team of researchers at Fudan University in Shanghai has developed a super-fast, picosecond-level non-volatile memory device. But what exactly is picosecond-level memory? It refers to memory that can read and write data within one-thousandth of a nanosecond or one-trillionth of a second.
The newly developed chip, named “PoX” (Phase-change Oxide), is capable of switching at 400-picoseconds, substantially surpassing the previous world record of 2 million operations per second.
