Abstract
A memory device and method of operating the same are disclosed. Generally, the device includes an array of Ferro-electric Random Access Memory cells. Each cell includes a first transistor coupled between a bit-line and a storage node (SN) and controlled by a first wordline (WL), a second transistor coupled between a reference line and the SN and controlled by a second wordline (WL), and a ferro-capacitor coupled between the SN and a plateline. The device further includes a sense-amplifier coupled to the bit-line and reference line, and a processing-element configured to issue control signals to WL, WL, the plateline and the sense-amplifier. The cell is configured and operated to generate a bit-level reference in which a first voltage pulse is applied to the plateline during a read cycle for the data pulse and a second voltage pulse serves as a reference pulse and as a clear pulse.
