To write to memory, the row is opened and a given column's sense amplifier is temporarily forced to the desired state, so it drives the bit line, which charges the capacitor to the desired value. Due to the positive feedback, the amplifier will then hold it stable even after the forcing is removed. During a write to a particular cell, the entire row is read out, one value changed, and then the entire row is written back in, as illustrated in the figure to the right. FANUC A20B-2902-0461
