Abstract
Memory devices and methods are disclosed for reading a restoring data from and to ferroelectric memory cells, wherein a data bit is sensed from a data memory cell, a toggle bit is sensed from a toggle memory cell, and the sensed data bit is transferred to an IO line in either inverted form or non-inverted form according to the sensed toggle bit. The sensed data bit and the toggle bit are then inverted and restored to the data and toggle memory cells so as to mitigate or reduce cell imprint.
