Abstract:
1. A non-volatile memory device comprising: an electrically polarizable dielectric memory material with ferroelectric or electret properties and capable of exhibiting hysteresis and remanence, wherein the memory material comprises one or more polymers, wherein the memory material is provided in contact with a first set and a second set of respective electrodes for write, read and erase operations, wherein a memory cell with a capacitor-like structure is defined in the memory material and can be accessed direct or indirectly via the electrodes, wherein memory cells in the memory device form the elements of an active or passive matrix, wherein each memory cell can be addressed selectively for a write/read/erase operation establishing a desired polarization state in the memory cell or performing a polarization switching thereof, wherein a definite polarization state established in the memory cell ( the ferroelectric or electret memory material (
