1. A memory, comprising: a memory cell operable to generate a read signal; and a sense amplifier having an amplifier input node operable to receive the read signal, the sense amplifier comprising: a first differential amplifier having a first input node coupled to the amplifier input node, a second input node operable to receive a reference signal, and an output node, and a feedback transistor having a control node operable to receive a bias signal for causing the feedback transistor to operate in a triode zone, a first conduction node coupled to the output node, and a second conduction node coupled to the input node.
