Abstract
A FeSRAM cell includes (a) first and second inverters between a power supply voltage and a ground reference cross-coupled to each other, the first and second cross-coupled inverters providing first and second data terminals; (b) first and second select transistors respectively coupled to the first and second data terminals to control access to the first second data terminals; and (c) first and second ferroelectric capacitors coupled between a first plate line and respectively the first and second data terminals, the first plate line receiving a negative programming voltage having a magnitude greater than the power supply voltage to allow programming one of the first and second ferroelectric capacitors into a first non-volatile programmed state.
