Abstract:
A method for controlling a read access of a memory cell of a dynamic random access memory device, each memory cell being connected to a bit line and associated with a read/rewrite amplifier connected between the bit line and a corresponding reference bit line, the method comprising:precharging the bit line and the corresponding reference bit line for a selected memory cell to a precharge voltage reading and refreshing contents of the selected memory cell based upon an activated read/rewrite amplifier associated therewith; and connecting at least one first capacitor previously charged to a charging voltage greater than the precharge voltage to the bit line of the selected memory cell, and connecting at least one second capacitor previously charged to a charging voltage greater than the precharge voltage to the corresponding reference bit line of the selected memory cell between the precharging and the reading and refreshing.
