  • Patent number: 10026620
    Abstract: The present invention relates to the growth of a native oxide layer on a surface of a silicon substrate. Deep ultraviolet (UV) light is irradiated to thereby effectively improve the quality of the native oxide layer. By improving the quality, the difficulty of the surface treatment of a cross-section sample for scanning capacitance microscopy (SCM) is improved. The life cycle and reliability of the sample are also improved with enhanced reproducibility for the measurement of SCM. Thus, the present invention provides an improved method and an apparatus using the same to prepare a cross-sectional sample for SCM. The feasibility and the concrete method for enhancing oxide layer quality on a silicon substrate surface by UV light irradiation under a humidity-controlled environment are established. The optimum parameters of irradiation time for n-type and p-type samples are made.

  • Patent number: 9898216
    Abstract: The present invention relates to a data storage system and specific command execution method thereof, which is applied to a memory storage system. When a memory manager receives an command from a host system, it can judge whether the command is a normal command or a specific command. If the command is the specific command, read a first logic sector address, an accessible data length and a second logic sector address in the specific command, and duplicate the first logic sector address pointing to the physical storage address of the stored data reading to a memory buffer; and move physical storage address pointing to that from the first logic sector address to the second logic sector address. It can achieve both data reading and data moving by one specific command.

  • Patent number: 9806740
    Abstract: A device for data compression includes a processing unit, a temporary memory, and a storage device. The temporary memory is used to temporarily store data to be compressed. The storage device includes multiple physical blocks. Each physical block has a same volume size. The processing unit compresses the to-be-compressed data, generates compressed data, and stores the compressed data into one of the physical blocks. The processing unit compares a data size of the compressed data and a volume size of one physical block, and when the data size of the compressed data is smaller than the volume size, the processing unit stores remnant data into the same physical block as the compressed data stored in, wherein the total data size of the remnant data plus the compressed data is equal to the volume size of the physical block both are stored in.

  • Publication number: 20170115905
    Abstract: The present invention provides a data storage system and method. A controller is connected to a plurality of disk arrays, and each disk array is provided with a data protection unit for data protection. When one disk drive of one of the disk arrays is damaged, this disk array is defined as a damaged disk array, while other disk arrays without disk drives being damaged are defined as at least one normal disk array. The controller stops to write a new written data into the damaged disk array, while write the new written data into the normal disk arrays. The new written data will be protected by the data protection units of the normal disk arrays. Thereby, continuous data protection for the new written data by the data protection units together with preservation of storage performance of the system, after the disk drive is damaged, may be achieved.
