Patent ID: 8158973

Claim:
An organic memory array comprising: a substrate; a first dielectric layer disposed over the substrate and a second dielectric layer disposed over the first dielectric layer, wherein one of said first and second dielectric layers consists of a ferroelectric dielectric material having opposing first and second surfaces, and the other of said first and second dielectric layers consists of an organic dielectric material having opposing first and second surfaces; a plurality of pixels, each of said plurality of pixels including: a ferroelectric field effect transistor (FeFET) including a first source electrode, a first drain electrode, and a first organic semiconductor portion, disposed in a first channel region separating said first source electrode and said first drain electrode, wherein said first source electrode, said first drain electrode, and said first organic semiconductor portion are disposed on said first surface of said ferroelectric dielectric material layer, said ferroelectric field effect transistor further including a first gate electrode disposed on said second surface of said ferroelectric dielectric material layer and positioned opposite to said first channel region; and a thin-film organic field effect transistor (FET) including a second source electrode, a second drain electrode, and a second organic semiconductor portion disposed in a second channel region separating said second source electrode and said second drain electrode, wherein said second source electrode, said second drain electrode, and said second organic semiconductor portion are disposed on said first surface of said organic dielectric material layer, said organic FET further including a second gate electrode disposed on said second surface of said organic dielectric material layer and positioned opposite to said second channel region, and wherein said second source electrode is electrically connected to the first gate electrode of said ferroelectric field effect transistor; and means for applying a write select signal to the second gate electrode of a selected pixel of said plurality of pixels and a write pulse signal to the second source electrode of said selected pixel such that said first write select signal turns on the organic FET of said selected pixel to pass the write pulse signal to the first gate electrode of said selected pixel, whereby an electric field generated by said first gate electrode in response to said write pulse signal portion generates a corresponding polarization of a portion of said ferroelectric dielectric material layer disposed between the first gate electrode and the first channel region of said selected pixel.
