  • Patent number: 11856879
    Abstract: A selector device for a memory cell in a memory array may include a first electrode, and a separator that include a first region of a single-composition layer of a mixed ionic-electronic conduction material with a first concentration of defects; and a second region of a single-composition layer of a transitional metal oxide with a second concentration of defects that is different from the first concentration of defects. The selector device may also include a second electrode, where the separator is between the first electrode and the second electrode.

  • Publication number: 20220109074
    Abstract: A selector device may include a first electrode, a tunneling layer, and a ferroelectric layer. The tunneling layer may be between the first electrode and the ferroelectric layer, and a thickness and dielectric constant of the tunneling layer relative to a thickness and dielectric constant of the ferroelectric layer may cause a depolarizing electric field induced in the first tunneling layer to be greater than or approximately equal to an electric field induced in an opposite direction by ferroelectric dipoles in the ferroelectric layer when a voltage is applied across the selector device. The device may also include a second electrode, and the ferroelectric layer may be between the tunneling layer and the second electrode. A second ing layer may also be added between the ferroelectric layer and the second electrode for bipolar selectors.

  • Publication number: 20210336134
    Abstract: A crested barrier memory and selector device may include a first electrode, a first self-rectifying, tunneling layer having a first dielectric constant, and an active, barrier layer that has a second dielectric constant and another self-rectifying, tunneling layer having a third dielectric constant. The first self-rectifying layer may be between the first electrode and the active layer. The second dielectric constant may be at least 1.5 times larger than the first dielectric constant. The device may also include a second electrode, where the active, barrier layer is between the first self-rectifying, tunneling layer and the second electrode.

  • Patent number: 11158791
    Abstract: A selector device for a memory cell in a memory array includes a first electrode, a second electrode, and a separator between the first electrode and the second electrode. The separator includes a mixed ionic-electronic conduction material with first ions having a first charge such that the first ions respond to a voltage applied between the first electrode and the second electrode by moving away from the first electrode. The separator is doped near the second electrode with second ions having a second charge that opposes the first charge.
