Claim:
1. A semiconductor device including: a physical parameter sensing circuit configured to sense a variation of a physical parameter; an applying parameter generating circuit coupled to the physical parameter sensing circuit, configured to adjust an applying parameter based on the variation of the physical parameter based on a transfer function which defines a relationship between the physical parameter and the applying parameter; and a main circuit, coupled to the physical parameter sensing circuit and the applying parameter generating circuit, wherein the main circuit comprises a plurality of memory cells each including a memory element and a selector coupled to the memory element, the transfer function comprises a temperature effect of the memory element and/or the selector, wherein the applying parameter generated by the applying parameter generating circuit is used to compensate effects on operations of the main circuit caused by the variation of the physical parameter, wherein if the physical parameter sensing circuit senses that a temperature is changed from a lower temperature to a higher temperature, the applying parameter generating circuit generates a lower reading bias voltage to a bit line coupled to one of the plurality of the memory cells and the same reference current for deciding a state of the one of the plurality of the memory cells at the same time, the lower reading bias voltage generated by the applying parameter generating circuit to the bit line at the higher temperature is lower than a higher reading bias voltage generated by the applying parameter generating circuit to the bit line at the lower temperature.
