Elevated pore phase-change memory

This invention relates generally to memories that use phase-change materials. An elevated phase-change memory cell facilitates manufacture of phase-change memories by physically separating the fabrication of the phase-change memory components from the rest of the semiconductor substrate. In one embodiment, a contact in the substrate may be electrically coupled to a cup-shaped conductor filled with an insulator. The conductor couples current up to the elevated pore while the insulator thermally and electrically isolates the pore.
