  • Patent number: 8209464
    Abstract: A management method, a management apparatus, and a controller for memory data access are provided. The management apparatus is disposed between a host and a device for managing the data transmitted between the host and the device, wherein the management apparatus includes a control unit and a storage unit. When the control unit receives a data writing command from the host, it searches for a set mapped to the data in the storage unit and updates the data in the set. Then, the control unit collects the other parts of the data in the storage unit and the device, integrates all parts of the data, and writes the integrated data into the device. Accordingly, the efficiency in data transmission can be improved, and the number of data writing operations can be reduced so that the lifespan of the device can be prolonged.

  • Patent number: 7187583
    Abstract: A method of a flash memory storage device using a copy back command is provided. An error correction rule is adopted to determine whether or not data errors occurred in the un-amended data stored in the page, wherein when it is determined that data errors has occurred in the un-amended data, then a data transfer command is executed, thereby enabling the flash memory storage device to use the block having a faster transferring speed to executing the copy back command. Thus, the data in the flash memory storage device is not only correct and complete but also the stability of the system is promoted.

    Abstract: Gas distribution systems for deposition processes and methods of using the same. A substrate support member holding a substrate is disposed in a processing chamber. A plurality of first and second gas nozzles is connected to a gas distribution ring disposed in the processing chamber. The first gas nozzles provide a first reactant gas and include at least first and second outlet apertures. The second gas nozzles provide a second reactant gas and include third outlet apertures. The first outlet aperture is larger than the second outlet aperture, such that the first gas nozzle with the first outlet aperture creates an increased gas flow adjacent to a determined portion of the substrate to increase deposition from the first reactant gas on the determined portion of the substrate.
