Abstract
A static RAM has for each row of cells a bit line and an inverted bit line. For allowing the current data being driven to each cell to be instantaneously stopped and for allowing the (inverted) bit line to go back to a safe non-writing condition two resettable delay chains are provided between a buffering element that has mutually logically inverse data outputs. Each chain has a first sequence of alternating inverter gate series feeding a second sequence of one or more inverters. At the end of a write cycle the gates are reset in parallel, thus shortening the delay to about that of the second sequence only. In this way operating margins are retained.
