  • Nonvolatile storage device with NCQ supported and writing method for a nonvolatile storage device
    Patent number: 8583854
    Abstract: A nonvolatile storage device buffers multiple write commands and selects one or more therefrom according to a choosing policy to execute in priority, so as to increase the probability of continuously executing write commands corresponding to an identical smallest erasable unit, thereby reducing the frequency of backup, erasing and copyback operations and improving the efficiency of the nonvolatile storage device.
    Type: Grant

  • Virtual SATA port multiplier, virtual SATA device, SATA system and data transfer method in a SATA system
    Patent number: 8135895
    Abstract: A virtual SATA port multiplier and a virtual SATA device are provided for a SATA system. The virtual SATA port multiplier uses a SATA physical layer for data transfer between it and a SATA host, and a non-physical layer for direct data transfer between it and the virtual SATA device. Since the data transfer between the virtual SATA port multiplier and the virtual SATA device is not carried out by way of SATA physical layers, no physical layer circuits are required accordingly, thereby reducing the manufacturing cost, power consumption and hardware size of the SATA system.

  • Nonvolatile memory system and method of decentralizing the peak current in a nonvolatile memory system
    Patent number: 8090898
    Abstract: A nonvolatile memory system has a controller chip connected to a memory medium and several nonvolatile memory chips. The memory medium stores program codes for the controller chip to distribute an operation of the nonvolatile memory chips upon an instruction over time, so as to decentralize the peak current caused by the operation and thereby improve the stability of the system.
