Abstract
The present disclosure relates to a non-volatile ferroelectric memory and a method of preparing the same. The ferroelectric memory includes a ferroelectric storage layer, a first electrode and a second electrode; the first electrode and the second electrode each include a buried conductive layer formed by patterning in a surface of the ferroelectric storage layer and an electrode layer formed on the buried conductive layer; and when a write signal in a certain direction is applied between the first electrode and the second electrode, the electric domains of a part of the ferroelectric storage layer between a pair of the buried conductive layers are enabled to be reversed, so that a domain wall conductive passage that electrically connects the first electrode and the second electrode can be established.
