A memory is disclosed that includes a plurality of memory cells, a plurality of sense amplifiers for reading data of the memory cells, and a voltage regulator coupled to the plurality of sense amplifiers. The voltage regulator includes a reference sense amplifier, a current injector, and a current injector control circuit. The current injector control circuit controls an amount of current provided by the current injector to an output node of the voltage regulator based on a voltage of the reference sense amplifier.
