ABSTRACT:
An over-driven access method and device for ferroelectric memory. When accessing the data stored in a ferroelectric memory, the invention further provides an over-driven current to slightly reduce/raise the voltages in bit lines BL and BL′ to further enlarge the voltage difference therebetween after having raised the plate-line/bit-line voltage using the plate-line/bit-line driven method.
