A method for fabricating a phase change memory pore cell that includes forming a bottom electrode, forming a first dielectric layer on the bottom electrode, forming a sacrificial layer on the first dielectric layer, forming an isolation layer on the sacrificial layer, and forming a second dielectric layer on the isolation layer. The method further includes forming a via overlying the bottom electrode, the via extending to the sacrificial layer, etching through the sacrificial layer to the first dielectric layer to form a pore defined extending through the sacrificial layer and the first dielectric layer, depositing phase change material on the sacrificial layer and into the pore and removing the phase change material formed outside the pore, removing the sacrificial layer to expose the pore, the pore being vertically aligned, and forming a top electrode over the pore.

A method of forming an antifuse forms a material layer and then patterns the material layer into a fin. The center portion of the fin is converted into a substantially non-conductive region and the end portions of the fin into conductors. The process of converting the center portion of the fin into an insulator allows a process of heating the fin above a predetermined temperature to convert the insulator into a conductor. Thus, the fin-type structure that can be selectively converted from an insulator into a permanent conductor using a heating process.

A method for operating a memory cell. Memory cells represent binary values by storing a characteristic parameter. The method of memory cell operation entails receiving a binary value to be stored by a memory cell. A determining operation determines a target discharge time corresponding to the binary value. The target discharge time being the time needed to discharge a pre-charged circuit through the said memory cell to a predetermined level. A storing operation stores a characteristic parameter in the memory cell such that an electron discharge time through an electronic circuit formed, at least partially, by the memory cell, is substantially equal to the target discharge time.

An example embodiment disclosed is a method for fabricating a phase change memory cell. The method includes forming a non-sublithographic via within an insulating substrate. The insulating substrate is embedded on the same layer as a first metalization layer (Metal 1) of a semiconductor wafer, and includes a bottom and a sidewall. A sublithographic aperture is formed through the bottom of the non-sublithographic via and extends to a buried conductive material. The sublithographic aperture is filled with a conductive non-phase change material. Furthermore, phase change material is deposited within the non-sublithographic via.
