Abstract
An embodiment of the present memory cell a first layer of a chosen conductivity type, and a second layer which includes ferroelectric semiconductor material of the opposite conductivity type, the layers forming a pn junction. The first layer may be a conjugated semiconductor polymer, or may also be of ferroelectric semiconductor material. The layers are provided between first and electrodes. In another embodiment, a single layer of a composite of conjugated semiconductor polymer and ferroelectric semiconductor material is provided between first and second electrodes. The various embodiments may be part of a memory array.
