ABSTRACT:
Provided are an electric field read/write device and a method of driving an electric field read/write device. The method including an electric field read/write head comprising a resistance region disposed between a source region and a drain region and a writing electrode disposed on the resistance region, wherein the method includes: applying a controlling voltage to the writing electrode, wherein the controlling voltage is smaller than a threshold voltage which causes polarization of a recording medium, and reproducing data recorded in the recording medium according to change of an amount of a current flowing through the resistance region according to a polarization direction of electric domains of the recording medium.
