How PMCm Works (cont)

The electrodeposit acts as a conducting link between the electrodes and hence the resistance of the device can be altered by many orders of magnitude via this non-volatile electrically-stimulated deposition process. A reverse bias will cause dispersion of the link, returning the device to a high resistance state and this write-erase cycle may be repeated many tens of millions of times per second. This reversible switching effect and the associated large change in resistance of the device is the basis of the Programmable Metallization Cell memory (PMCm) technology.
