A read-amplifier circuit includes a core with a first input and a second input that are intended to receive in a measurement phase a differential signal arising from a first bit line and from a second bit line of the memory device. The circuit also includes a memory element with two inverters coupled in a crossed manner. The first and second inputs are respectively connected to two of the power supply nodes of the inverters via two transfer capacitors. A first controllable circuit is configured to temporarily render the memory element floating during an initial phase preceding the measurement phase and during the measurement phase.
