Researchers examine perovskite material for non-volatile phase change memory
Researchers from Japan's Tohoku University and University of Tsukuba have reported a breakthrough in the development of non-volatile phase change memory−a type of electronic memory that can store data even when the power is turned off−using a perovskite-derivative nickelate material.
Until now, phase change memory has primarily been developed using chalcogenides, a group of materials known to exhibit reversible electrical changes when they transition between their crystalline and amorphous states. However, in their recent study, the researchers reported thermally reversible switching of room-temperature electrical resistivity in a layered nickelate−potentially offering better performance and superior sustainability.
