Abstract
A non-volatile memory device with a built-in laser indicator. The non-volatile memory device includes a connective port, a buffer, a non-volatile memory unit, a memory controller, a battery and a laser indicator. The connective port connects electrically to a host machine. The host machine transfers data and provides power to the connective port through an external bus. The buffer holds the data transmitted to the connective port temporarily. The memory controller controls the transfer of data from the buffer into the non-volatile memory unit. The battery receives host power and stores up some host power to serve as backup power. The battery also provides the power for driving the laser indicator.
