A memory cell array with open bit line structure includes a first sub memory cell array, a second sub memory cell array, a sense-amplifier/precharge circuit, first capacitors and second capacitors. The first sub memory cell array is activated in response to a first word line enable signal, and the second sub memory cell array is activated in response to a second word line enable signal. The sense-amplifier/precharge circuit is connected to the first sub memory cell array through first bit lines and to the second sub memory cell array through second bit lines, and the sense-amplifier/precharge circuit precharges the first bit lines and the second bit lines and amplifies data provided from the first sub memory cell array and the second sub memory cell array.
