Abstract
A resistive element of a resistive memory cell. The resistive element includes a contact in communication with a substrate. A bottom electrode is formed on the contact. A transitional metal oxide layer is formed on the bottom electrode. The transitional metal oxide layer includes oxygen vacancies configured to receive donor oxygen atoms. A transition layer formed on the transitional metal oxide layer includes donor oxygen atoms. A reactive metal layer is formed on the transition layer. A top electrode is formed on the transitional metal oxide layer. The transition layer is configured to provide the donor oxygen atoms to the transitional metal oxide layer in response to a voltage being applied to the top electrode.
