A memory storage device having a rewritable non-volatile memory module, a first connection interface unit, a second connection interface unit, a power management circuit and a memory control circuit unit is provided. When an external power supply device is electrically connected to the second connection interface unit, the power management circuit receives a second power supply voltage from the external power supply device via the second connection interface unit, supplies an operation voltage to the rewritable non-volatile memory module and the memory control circuit unit and supplies the second power supply voltage to a host device. When the external power supply device is electrically disconnected with the second connection interface unit, the power management circuit receives a first power supply voltage from the host device via the first connection interface unit and supplies the operation voltage to the memory control circuit unit and the rewritable non-volatile memory module.

Memory storage device and power management method thereof

A non-volatile memory storage apparatus having a connector, an energy storage circuit, a power regulator and supply circuit, a non-volatile memory module, a memory controller and a buffer memory is provided. The power regulator and supply circuit is configured for transforming an output voltage from the energy storage circuit into a first voltage used for the non-volatile memory module and a second voltage used for the memory controller and the buffer memory. The memory controller is configured for writing data stored temporarily in the buffer memory into the non-volatile memory module with a special writing mode when receiving a detecting signal indicating that an input voltage is continuously smaller than a predetermined voltage for a predetermined period or receiving a detecting signal indicating that an inactive status of the connector or receiving a suspend mode signal, a warm reset signal or a hot reset signal from a host system.

A method and a system for protecting data, a storage device, and a storage device controller are provided. In the present method, when a host accesses data in the storage device, whether the host performs a play operation or a copy operation on the data is first determined. If the host performs the play operation on the data, the storage device continues to execute the play operation so as to allow the host to access the data. On the other hand, if the host performs the copy operation on the data, the storage device executes an interference procedure so as to prevent or retard the data from being copied into the host.

Method and system for protecting data, storage device, and storage device controller

A flash memory storage apparatus is provided. The flash memory storage apparatus includes a substrate, a control and storage circuit unit, a ground lead, at least a signal lead, and a power lead. The control and storage circuit unit, the power lead, the signal lead, and the ground lead are disposed on the substrate, in which the power lead, the signal lead, and the ground lead respectively electrically connect to the control and storage circuit unit. Moreover, the flash memory storage apparatus further includes an extra ground lead electrically connected to the ground lead or a protrusion on the substrate, such that the ground lead first electrically connects to a host when the flash memory storage apparatus is plugged into the host.
