Abstract: A column decoder cell layout for use in a 1T/1C ferroelectric memory array includes a first column decoder section having two input nodes for receiving a first input/output signal and a first inverted input/output signal, two output nodes for providing a first bit line signal and a first inverted bit line signal, and a column decode node for receiving a column decode signal, a second column decoder section having two input nodes for receiving a second input/output signal and a second inverted input/output signal, two output nodes for providing a second bit line signal and a second inverted bit line signal, and a column decode node for receiving the column decode signal, wherein the width of the column decoder cell is substantially the same as the width of two columns of 1T/1C memory cells used in the array.
