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.
