Abstract
The disclosure relates to a sense amplifier comprising a cascode transistor and means for biasing the cascode transistor, supplying a control voltage to a gate terminal of the cascode transistor. The means for biasing the cascode transistor comprise means for isolating the gate terminal of the cascode transistor from the output of the voltage generator during a first period of the precharge phase, so as to boost the bitline voltage, then for linking the gate terminal to the output of the voltage generator during a second period of the precharge phase. Application in particular to sense amplifiers for non-volatile memories.
