Abstract
Resistive switching memory cells having filament-based switching mechanisms are provided. By way of example, resistive switching memory cells having resistive filaments constrained to a core of the cell are disclosed. In other examples, methods for fabricating resistive switching memory cells to constrain a conductive filament formed in the resistive switching memory cell to a central portion of core of the cell are disclosed.
