Abstract:
Methods, systems, and devices for operating a ferroelectric memory cell or cells are described. Prior to writing a logic value to a ferroelectric memory cell, a digit line of a ferroelectric memory cell may be biased to a first voltage, and a cell plate of the ferroelectric memory cell may be biased to a second voltage. A magnitude of a difference between the first voltage and the second voltage may be greater than a magnitude of a write voltage for the first ferroelectric memory cell. The magnitude of the difference between the first voltage and the second voltage may decrease the time to reach a write voltage for the ferroelectric memory cell. Several example cell plate drivers are also disclosed.
