Memristive device having a porous dopant diffusion element

摘要

A memristive device includes: a first electrode; a second electrode; a memristive matrix interposed between the first electrode and the second electrode; a porous dopant diffusion element in physical contact with the memristive matrix and in proximity to the first electrode and the second electrode; and a first mobile dopant species which moves through the porous dopant diffusion element in response to a programming electrical field. A method for using a memristive device having a porous dopant diffusion element includes applying a voltage bias to generate a programming electrical field such that dopants move through the porous dopant diffusion element, thereby changing the distribution of dopants within a memristive matrix to form a first state; removing the voltage bias, the dopants being substantially immobile in the absence of the programming electrical field; and applying a reading energy to the memristive device to sense the first state.
