Patent ID: 8416621

Claim:
A non-volatile memory storage apparatus, comprising: a connector, configured to couple to a host system; an energy storage circuit, configured to receive an input voltage and provide an output voltage; a power regulator and supply circuit, coupled to the energy circuit and configured to transform the output voltage into a first voltage and a second voltage; a non-volatile memory module, coupled to the power regulator and supply circuit and operated with the first voltage; a memory controller, coupled to the connector, the energy storage circuit and the power regulator and supply circuit, wherein the memory controller is operated with the second voltage; and a buffer memory, coupled to the memory controller and configured to temporarily store data, wherein the memory controller is configured to write the data stored temporarily in the buffer memory into the non-volatile memory module when receiving a signal, wherein the signal is a detection signal indicating that the input voltage is smaller continuously than a predetermined voltage for a predetermined period, a detection signal indicating that an inactive status of the connector, or a suspend mode signal, a warm reset signal or a hot-reset signal from the host system.
