Abstract: The present disclosure discloses a data readout circuit of a RRAM and a RRAM circuit. The data readout circuit of the RRAM comprises: an adaptive current sense amplifier (CSA) and a reference current generator, the adaptive CSA is configured to electrically connect to the RRAM, and the adaptive CSA is electrically connected to the reference current generator; the reference current generator is configured to generate a basic reference current; the adaptive CSA is configured to obtain a reference current according to the basic reference current and a bit-line current of the RRAM; and the adaptive CSA is configured to compare the size of the reference current and that of the bit-line current so as to read out stored data. The present disclosure can improve the problem of data readout error due to the degradation of high resistance state of the RRAM.

Abstract: A battery status indication method, A battery status indication apparatus, and a mobile device are provided. The battery status indication method includes: obtaining a power level and a heat state of a battery, the heat state including an unheated state and a heating state; determining a display mode of indicator lights according to the power level and the heat state of the battery; and controlling the indicator lights to display according to the display mode to indicate the power level and the heat state of the battery.
