Abstract:
A method for storing information in a memory device, the memory device comprising a plurality of memory elements produced by the steps comprising:(a) providing a silicon substrate, (b) forming a source region and a drain region in the substrate, (c) plasma depositing a plasma deposited memory storage layer on the substrate, the plasma deposited memory storage layer having an upper region and a lower region, (d) forming a metal electrode on the memory storage layer, (e) forming movable ions from the plasma deposited memory storage layer by heating the plasma deposited memory storage layer, storing information in the memory device by:(i) applying a first voltage to the metal electrode thereby moving the movable ions to the upper region of the plasma deposited memory storage layer, (ii) applying a second voltage to the metal electrode thereby moving the movable ions to the lower region of the plasma deposited memory storage layer.
