US Patent 7782691 Apparatus for guaranteed write through in domino read SRAM's

In a digital device for facilitating recovery of a precharged dot line, periodically precharged by a precharge signal, that has been prematurely discharged as a result of an early read condition, a data input signal 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 logic device that is responsive to the data input signal causes charge to be applied to the dot line when the data signal has the first value.
