Abstract:
A memory device, comprising:a circuit device defining a horizontal surface and a non-horizontal surface; a porous oxide over said circuit device, said porous oxide having a first thickness extending perpendicularly from said horizontal surface and a second thickness extending generally perpendicularly from said non-horizontal surface, wherein said second thickness is different from said first thickness, wherein said porous oxide comprises an oxide defining at least one pore, wherein said porous oxide comprises a plurality of silicon atoms and a plurality of oxygen atoms, wherein said plurality of silicon atoms and said plurality of oxygen atoms define a lattice constant, wherein at least one dimension of said at least one pore is greater than said lattice constant, and wherein said dimension of said at least one pore is at least 10 angstroms; and a dopant in at least one pore.
