    摘要: Systems and methods fatigue a ferroelectric memory device. Within a single cycle, a group of selected ferroelectric memory cells is fatigued by reading a first logical value from the cells while also writing a second logical value to the memory cells. The first logical value is temporarily stored into latches of sense amplifiers associated with the selected memory cells in order to decipher logical values. Subsequently, the first logical value is written back to the ferroelectric memory cells and a cycle of the fatigue operation is ended.

    摘要: An FeRAM memory array wherein the plate lines run in the direction of word lines is described that provides a reduced plate line resistance in arrays having a common plate line connection. The lower plate line resistance reduces the magnitude of negative spikes on the plate line to reduce the potential for FeCap depolarization. Two or more plate lines of a plurality of columns of memory cells are interconnected along a bit line direction. Some or all of the plate lines of one or more columns of dummy memory cells may also be interconnected to reduce the plate line resistance and minimize any increase in the bit line capacitance for the active cells of the array. The improved FeRAM array provides a reduced data error rate, particularly at fast memory cycle times.
