20100027365 | NON-VOLATILE MEMORY DEVICE CAPABLE OF SUPPLYING POWER - A non-volatile memory device capable of supplying power is provided. The non-volatile memory device includes an electrical storage device for supplying a stored power, a charging control circuit coupled to the electrical storage device, a non-volatile memory, an input/output (I/O) interface, and a power control circuit. The I/O interface connects an electronic apparatus for transmitting an external power output from the electronic apparatus to the non-volatile memory and the charging control circuit, such that the charging control circuit could control a charging current and a charging voltage of the electrical storage device. The power control circuit converts the stored power into a backup power, and monitors whether a voltage value of the external power is less than a predetermined value. If the result is positive, the power control circuit controls the charging control circuit to stop charging the electrical storage device, and outputs the backup power through the I/O interface. | 02-04-2010 |
