Electronic device and method to reduce power consumption during access

A method to reduce power consumption of an electronic device, wherein the electronic device comprises a first buffer, a second buffer, and a first multiplexer, and the first multiplexer is electrically connected between the first buffer and the second buffer, the method comprising:

• the first buffer receiving and storing first data when the first buffer is not full;
• the first buffer performing a First-In-First-Out (FIFO) operation on the first data;
• the second buffer receiving and storing second data when the first buffer is full;
• the second buffer performing the FIFO operation on the second data;
• and
• the first multiplexer receiving and outputting the second data from the second buffer to the first buffer after the first data are read from the first buffer.
