  • Memory controller, nonvolatile storage device, nonvolatile storage system, and data writing method
    Patent number: 7702846
    Abstract: A nonvolatile storage device is provided with a nonvolatile main storage memory whose erase size is larger than a cluster size, and a buffer, i.e. a nonvolatile auxiliary storage memory. At the time of writing data in the memory, the data is temporarily stored in the buffer, then, a plurality of data in the buffer are collectively taken out to be stored in the main storage memory. Data in an original block is saved in a write block in the main storage memory. Thus, the data can be written in the main storage memory at a high speed.

  • MEMORY CONTROLLER, NONVOLATILE STORAGE DEVICE, NONVOLATILE STORAGE SYSTEM, AND DATA WRITING METHOD
    Publication number: 20090055576
    Abstract: A nonvolatile storage device is provided with a nonvolatile main storage memory (114) whose erase size is larger than a cluster size, and a buffer (106), i.e. a nonvolatile auxiliary storage memory. At the time of writing data in the memory, the data is temporarily stored in the buffer (106), then, a plurality of data in the buffer (106) are collectively taken out to be stored in the main storage memory (114).
