1. A memory with variable operation voltage, comprising:

  • a first core memory module operated by a first control voltage for accessing a first data;

    a register for storing a plurality of control signals and selecting one among the control signals as a voltage control signal according to an input signal, wherein the register complies with a specification established by Joint Electron Device Engineering Council (JEDEC), wherein the register is different from the first core memory and the input signal is not determined according to the first control voltage; and

    a first voltage adjustment module electrically connected to the register, the first core memory module and an external voltage, respectively, so as to provide the first control voltage according to the voltage control signal and the external voltage, so that the first control voltage is adjustable according to the voltage control signal, wherein the first voltage adjustment module comprises;

    a first voltage source for draining power from the external voltage to provide a plurality of first voltages according to the external voltage; and

    a first voltage regulator for draining power from the external voltage to output the first control voltage according to a first reference voltage;

    wherein the first reference voltage is one among the plurality of first voltages.
