A ferroelectric random access memory (FRAM) with reduced cycle time. During a read cycle, plate line voltages are boosted to a voltage to both transfer charge from the selected row of FRAM cells to corresponding bit lines, and to fully polarize a data state in the selected FRAM cells. In one embodiment of the invention, the fully polarized data states is present in those cells that previously stored that data state; for those cells storing the opposite state, a write-back pulse is executed. In another embodiment of the invention, the fully polarized data state results for each of the selected memory cells, by applying a plate line boost voltage of a higher magnitude. Those cells that are to store the opposite data state, as may be determined following error correction, are written back with that data state. |
