Abstract
In a ferroelectric memory cell having a plate line, a word line and a bit line coupled to a sense amplifier, a sensing method includes the steps of precharging the bit line to a logic one voltage, setting the word and plate lines to an initial logic zero voltage, stepping the word line from the initial logic zero voltage to the logic one voltage, stepping the plate line from the initial logic zero voltage to the logic one voltage, activating the sense amplifier to resolve voltage developed on the bit line to a full logic voltage while the word and plate lines are at the logic one voltage, and returning the word and plate lines to the initial logic zero voltage.
