Abstract

A semiconductor memory includes a dynamic discharge circuit for the quick discharging of a power supply line to which a memory matrix row is connected when this power supply line changes over from the electrical selected state to the electrical rest state. A transistor which is rendered conductive by a dynamic potential difference which arises, due to the slow discharge of the power supply line, between this line and the selection circuit thereof, supplies a current for a brief period of time in order to achieve the quick discharging. The invention is typically used notably for the discharging of power supply lines of E.C.L.-type random access memories.
