Abstract
A memory device includes sense amplifier circuitry, a current sink and a resistive element. The sense amplifier circuitry is operable to evaluate data read from a memory array included in the memory device responsive to a bias voltage applied to the sense amplifier circuitry. The current sink is operable to sink a bias current. The resistive element couples the current sink to the sense amplifier circuitry. The bias voltage applied to the sense amplifier circuitry corresponds to the voltage drop across the resistive element and current sink as induced by the bias current.
