    Abstract: A memory device, a source line voltage adjuster and a source line voltage adjusting method thereof are provided. The source line voltage adjuster includes an operation amplifier, a current drainer and a current generator. The operation amplifier includes a first input end coupled to a common source line and a second input end for receiving a reference voltage. The operation amplifier generates an bias voltage. The current drainer drains a drain current from the common source line according to the bias voltage. The current generator provides an output current for the common source line. The current generator generates a first current according to the bias voltage, and generates a second current according to a reference current. The current generator generates the output current according to a difference of the second current and the first current.

    Abstract: One aspect of the technology is a memory device comprising a memory array, a sense circuit, and temperature compensated bias circuitry. The memory array is electrically coupled between a bit line bias circuit and a common source line. The bit line bias circuit generates a temperature compensated sense current through the memory array. The temperature compensated bias circuitry controls the bit line bias circuit to generate the temperature compensated sense current through the memory array.
