Abstract: A sense amplifier connected to first and second bit lines, comprising means for precharging said bit lines to a high voltage, means for connecting one or the other of the bit lines to a memory cell, said connection causing according to the state of the memory cell a maintaining of the bit line at the high voltage or a voltage reduction, first and second transistors respectively controlled by the first and second bit lines, and, in series with the first and second transistors, a controllable means for the current through the transistor controlled by the bit line connected to the memory cell to be greater than the current through the other transistor when the voltages of the two bit lines are at the high voltage.
