Abstract
The state of a volatile memory cell is set by grounding a power supply to the volatile memory cell and driving a first bit line to the volatile memory cell to a first defined state. The first defined state of the first bit line is controllable independently of a defined state of a second bit line to the volatile memory cell. A word line of the volatile memory cell is driven to a word line state, and the power supply to the volatile memory cell is ungrounded.
