We demonstrate interface-enhanced memristors (OxReRAM) tailored for cryogenic spin-qubit control. By engineering a sparse filament network, our devices achieve eight nonvolatile resistance levels with an ultra-low read noise rate of around 0.3 %. When embedded in a cryogenic gain stage with RL = 30 kΩ and Vin = 0.3 V, it will deliver a ±1 V output range and sub-100-μV resolution using only six memristors per channel. This single-line biasing architecture will reduce wires, paving the way for large-scalce quantum processors.
