A sense amplifier (15) that is configurable to operate in two modes in order to control a voltage swing on the sense amplifier output (40). The sense amplifier has two feedback paths (45 to 35) including a first feedback path (P101, N101, N133) having a transistor (N133) with a fast response time in order to allow the circuit to operate as fast as possible, and a second feedback path (P121, P102, N102, N121, N132, N131) for providing voltage swing control. In the first operating mode, the "turbo" mode, both feedback paths are in operation (BOOST = HIGH) to provide a higher margin of swing control, thus higher sensing speed. In the second operating mode, the "non-turbo" mode, only the first feedback path is in operation (BOOST = LOW) which allows for greater stability and a reduction in power consumption. |
