Abstract: A device maintains a state of a precharged dot line that is periodically precharged by a global precharge signal. The device includes a data input signal that can have a selected one of a first value and a second value. The first value is a value that would be reflected by the dot line being in a charged state. A precharge circuit is responsive to a global precharge signal and is configured to precharge the dot line. A guaranteed write through logic device is responsive to the data input signal. The guaranteed write through logic device ensures that charge is applied to the dot line whenever the data. A guaranteed write through inhibitor that is responsive to a write through gate signal is configured to inhibit selectively the guaranteed write through logic device from applying charge to the dot line when the write through gate signal is in a guarantee inhibit state.
