Scientists in Taiwan have made a flexible memory device, which they say could open up a new design approach for high performance flexible non-volatile resistive memory devices. Non-volatile devices are computer memory devices that can retain stored information even when not powered, for example read-only memory, flash memory, hard drives and floppy disks.
The team’s device consists of a single-layer donor-acceptor conjugated polymer fabricated on plastic polyethylene naphthalene. It displayed a low threshold voltage (±2V), low switching power (~100µW cm-2), large on/off memory window (104), good retention (>104s) and excellent endurance against electrical and mechanical stimuli, they say.
