To write to memory, the row is opened and a given column's sense amplifier is temporarily forced to the desired high or low voltage state, thus it drives the bit line to charge or discharge the cell storage capacitor to the desired value. Due to positive feedback, the amplifier will then hold it stable even after the forcing is removed. During a write to a particular cell, all the columns in a row are sensed simultaneously just as in reading, a single column's cell storage capacitor charge is changed, and then the entire row is written back in, as illustrated in the figure to the right.
