Abstract
In some embodiments, the present disclosure relates to an integrated chip. The integrated chip includes a bottom electrode disposed over a substrate and a top electrode disposed over the bottom electrode. A ferroelectric switching layer is arranged between the bottom electrode and the top electrode. The ferroelectric switching layer is configured to change polarization based upon one or more voltages applied to the bottom electrode or the top electrode. A seed layer is arranged between the bottom electrode and the top electrode. The seed layer and the ferroelectric switching layer have a non-monoclinic crystal phase.
