Abstract

See full text

An apparatus comprises field-effect transistor (FET) structures stacked horizontally and vertically in a three-dimensional memory array architecture, gates extending vertically and spaced horizontally between the plurality of FET structures, and a ferroelectric material separating the FET structures and the gates. Individual ferroelectric FETs (FeFETs) are formed at intersections of the FET structures, the gates, and the ferroelectric material. Another apparatus comprises a plurality of bit lines and word lines. Each bit line has at least two sides that are coupled with a ferroelectric material such that each bit line is shared by neighboring gates to form a plurality of FeFETs. A method of operating a memory array comprises applying a combination of voltages to a plurality of word lines and digit lines for a desired operation for a plurality of FeFET memory cells, at least one digit line having the plurality of FeFET memory cells accessible by neighboring gates.
