Abstract
Memory devices and memory cell groups therefor are disclosed, which comprise series connected ferroelectric (FE) memory cells accessible using a single bitline. The cells individually comprise a transistor and an FE capacitor where a single cell within the group or array is connected to a bitline for external access during read, write, and/or restore operations. Methods are also disclosed for reading target cells in a memory cell group.
