Classification: CPC G  H | IPC G  H

Claim 0:
1. An isolation circuit system, comprising a power management unit, a digital logic circuit and an isolation circuit, wherein
the power management unit is configured to output a first signal to a digital logic circuit when power down is detected in a first circuit area, and output a second signal to the digital logic circuit when no power down is detected in the first circuit area;
the digital logic circuit is configured to perform logical processing on the first signal received from the power management unit before outputting an isolation signal to the isolation circuit, and perform logical processing on the second signal received from the power management unit before outputting a connection signal to the isolation circuit; and
the isolation circuit is configured to simultaneously receive an interactive signal from the first circuit area and the isolation signal from the digital logic circuit and block the interactive signal, or to simultaneously receive the interactive signal from the first circuit area and the connection signal from the digital logic circuit and output the interactive signal to a second circuit area after the interactive signal is processed through voltage stabilization,
wherein the interactive signal outputted from the first circuit area comprises a write enable signal and a data signal, and
wherein the second circuit area comprises a register, and the isolation circuit is configured to output the interactive signal to the register of the second circuit area after the interactive signal is processed through the voltage stabilization when simultaneously receiving the interactive signal from the first circuit area and the connection signal from the digital logic circuit.
