Abstract
A ferroelectric tunnel junction (FTJ) memory device may include a first electrode and a ferroelectric layer comprising ferroelectric dipoles that may generate a first electric field. The first electric field may be oriented in a first direction when the device operates in an ON state. The device may also include a barrier layer that may generate a depolarizing second electric field that may be oriented in a second direction opposite of the first direction when the device operates in the ON state. The device may further include a second electrode. The first electrode and the second electrode may generate a third electric field that is oriented in the first direction when the device operates in the ON state.
