Abstract
A nonvolatile memory system is described. The system includes ferroelectric memory cells each comprising a pair of metal plates and a ferroelectric material therebetween. Data are stored in the cells by applying an electric field corresponding to the desired data value across a given cell, thereby setting the polarity of the ferroelectric material to a given state. A datum is read from a cell by a mechanical force to the ferroelectric material and sensing charge induced on one of the cells.
