An apparatus and method of operating an open digit line and a folded digit line DRAM memory array having a plurality of memory cells wherein, in a plan view, each memory cell, in one embodiment, has an area of 6F2. One method comprises, storing a first bit in a first memory cell and storing a second bit that is complementary to the first bit in a second memory cell. The first bit and the second bit form a data bit. The data bit is read by comparing a voltage difference between the first memory cell and the second memory cell.
