Abstract:
In one embodiment, a device is described for using ferroelectric material in a memory cell without a selector device. In another embodiment, a method of operating a ferroelectric memory cell without a selector device is described. Other embodiments are likewise described.

Claim (Index 11):
A method of operating a ferroelectric memory cell including at least one word-line and at least one bit-line, the ferroelectric memory cell comprising a ferroelectric capacitor of ferroelectric material such that polarization of the ferroelectric memory cell is capable of being switched to an opposite polarization via a sufficient voltage signal level difference of opposite polarity generated across the ferroelectric memory cell, the ferroelectric material further being such that polarization of the ferroelectric memory cell does not change unless the sufficient voltage signal level difference generated exceeds a coercive voltage signal level value associated with the particular ferroelectric material, the method comprising:\n switching the at least one word-line between a second word-line voltage signal level and a first word-line voltage signal level; the first word-line voltage signal level to exceed the second word-line voltage signal level; switching the at least one bit-line between a first bit-line voltage signal level and a second bit-line voltage signal level; the first bit-line voltage signal level to exceed the second bit-line voltage signal level; wherein the first word-line voltage signal level comprises a voltage signal level of about half of the sufficient voltage level difference in a first polarity, and the second bit-line voltage signal level comprises a voltage signal level of about half of the sufficient voltage level difference in a second polarity; and wherein the switching of the at least one word-line and the at-least one bit line comprises generating a voltage signal level difference across the selector-free ferroelectric memory cell that exceeds a coercive voltage signal level value associated with the particular ferroelectric material such that polarization of the ferroelectric memory cell is switched to an opposite polarization.
