    摘要: A programmable metallization device, comprises a first electrode; a memory layer electrically coupled to the first electrode and adapted for electrolytic formation and destruction of a conducting bridge therethrough; an ion-supplying layer containing a source of ions of a first metal element capable of diffusion into and out of the memory layer; a conductive ion buffer layer between the ion-supplying layer and the memory layer, and which allows diffusion therethrough of said ions; and a second electrode electrically coupled to the ion-supplying layer. Circuitry is coupled to the device to apply bias voltages to the first and second electrodes to induce creation and destruction of conducting bridges including the first metal element in the memory layer. The ion buffer layer can improve retention of the conducting bridge by reducing the likelihood that the first metallic element will be absorbed into the ion supplying layer.

    摘要: A programmable metallization device comprises a first electrode and a second electrode, and a first dielectric layer, a second dielectric layer, and an ion-supplying layer in series between the first and second electrodes. In operation, a conductive bridge is formed or destructed in the first dielectric layer to represent a data value. During read, a read bias is applied that is sufficient to cause formation of a transient bridge in the second dielectric layer, and make a conductive path through the cell if the bridge is present in the first dielectric layer. If the bridge is not present in the first dielectric layer during the read, then the conductive path is not formed. Upon removal of the read bias voltage any the conductive bridge formed in the second dielectric layer is destructed while the conductive bridge in the corresponding other first dielectric layer, if any, remains.

    摘要: A programmable metallization device comprises a first electrode and a second electrode, and a dielectric layer, a conductive ion-barrier layer, and an ion-supplying layer in series between the first and second electrodes. In operation, a conductive bridge is formed or destructed in the dielectric layer to represent a data value using bias voltages having the same polarity, enabling the use of diode access devices. To form a conductive bridge, a bias is applied that is high enough to cause ions to penetrate the conductive ion-barrier layer into the dielectric layer, which then form filaments or bridges. To destruct the conductive bridge, a bias of the same polarity is applied that causes current to flow through the structure, while ion flow is blocked by the conductive ion-barrier layer. As a result of Joule heating, any bridge in the dielectric layer disintegrates.
