Abstract
A memory storage apparatus having a plurality of operating modes is provided. The memory storage apparatus includes a memory control circuit and a memory cell array circuit. The memory control circuit controls the memory storage apparatus to operate in one of the operating modes. The memory control circuit controls the memory storage apparatus to operate in a first operating mode and controls the memory storage apparatus to switch from the first operating mode to a second operating mode to refresh storage data of the memory cell array circuit. The memory storage apparatus operates in a third operating mode to refresh storage data in the memory storage apparatus. An operating voltage of the memory storage apparatus operating in the second operating mode is smaller than an operating voltage of the memory storage apparatus operating in the third operating mode.
