Abstract
Apparatus and methods are described for a multi-level FeRAM memory device. Using write and read circuits associated with the memory device, multiple data states may be written to and read from the ferroelectric memory device which are associated with a single polarization direction, thereby allowing for a single cell to contain more than one bit of data.
