Diode-and-fuse memory elements for a write-once memory comprising an anisotropic semiconductor sheet

摘要

A donor/acceptor-organic-junction sheet employed within an electronic memory array of a cross-point diode memory. The donor/acceptor-organic-junction sheet is anistropic with respect to flow of electrical current and is physically unstable above a threshold current. Thus, the volume of the donor/acceptor-organic-junction sheet between a row line and column line at a two-dimensional memory array grid point serves both as the diode component and as the fuse component of a diode-and-fuse memory element and is electrically insulated from similar volumes of the donor/acceptor-organic-junction sheet between neighboring grid point intersections.
