Abstract
Methods, systems, techniques, and devices for operating a ferroelectric memory cell or cells are described. Groups of cells may be operated in different ways depending, for example, on a relationship between cell plates of the group of cells. Cells may be selected in pairs in order to accommodate an electric current relationship, such as a short, between cells that make up the pair. Cells may be arranged in cell plate groups, and a pair of cells may include a first cell plate from one cell plate group and a second cell plate from the same cell plate group or from another, adjacent cell plate group. So a pair of cell plates may include cell plates from different cell plate groups. The first and second cell plates may be selected as a pair or a group based at least in part on the electric current relationship between the cell plates.
