Making flexible memories at room temperature
Researchers in the US and Korea say they have developed a
new way to make a flexible, resistive random access memory (RAM) device in a
room-temperature process – something that has proved difficult to do until now.
The device, which is based on nanoporous tungsten oxide, is a bipolar switch
and has a high on/off current ratio of more than 105. It can also be
bent and unbent over 103 cycles without suffering any significant
loss in performance.
