Control circuit, battery having the control circuit and battery control method

A battery comprising:

• a battery core;
• and
• a control circuit for controlling the battery core, the control circuit comprising:
• a power input terminal electrically connected to the battery core;
• a ferromagnetic random access memory, the ferromagnetic random access memory having a dynamic mode and a non-volatile mode;
• and
• a control unit electrically connected with the ferromagnetic random access memory and the power input terminal, the control unit being configured to:
• acquire state information of the battery core and store the state information to the ferromagnetic random access memory, and
• switch on or off an electrical connection between the power input terminal and the battery core to switch the ferromagnetic random access memory to the dynamic mode or the non-volatile mode.
