Memory sense amplifier voltage modulation. An embodiment of a an apparatus includes a memory including a sense amplifier; a first node for an high voltage rail for the sense amplifier and a second node for a low voltage rail for the sense amplifier; one or more elements to provide a first voltage to the first node and a second voltage to the second node; and a voltage control engine to control the one or more elements, where the voltage control engine is to independently set a value of the first voltage and a value of the second voltage over time.
