Memory with variable operation voltage and the adjusting method thereof

An operation voltage adjustment method for a memory, comprising:

• providing an external voltage;
• generating a control signal according to a lookup table and an input signal;
• and
• acquiring power from the external voltage and providing a first control voltage to a core memory module by a first voltage adjustment module according to the control signal.

A memory with variable operation voltage, comprising:

• a plurality of core memory modules;
• a plurality of peripheral circuitries;
• a register complying with a specification established by Joint Electron Device Engineering Council (JEDEC), for storing a plurality of control signals;
• and
• a voltage adjustment module respectively electrically connected to the register, the core memory modules, the peripheral circuitries, and an external voltage, so as to provide control voltages for the core memory modules and the peripheral circuitries according to the control signals and the external voltage.
