  • Publication number: 20070266297
    Abstract: A controller for controlling an access of a non-volatile memory having an error-correcting code area and a data area is provided. The controller includes an error-correcting module and a first inverting circuit electrically connected to the error-correcting module for inverting data and error-correcting codes corresponding to the data. When the controller both writes all 0×FF data in the data area and writes all 0×FF error-correcting codes in the error-correcting code area, the first inverting circuit inverts the all 0×FF data and the all 0×FF error-correcting codes into all 0×00 data and all 0×00 error-correcting codes, respectively.

  • Publication number: 20050138314
    Abstract: The write-protected micro memory device of the present invention comprises at least one flash memory that is divided into one or multiple blocks, and the single chip flash memory controller has a write-protected parameter. The write-protect parameter can be set particularly for protecting data of certain block(s) of the flash memory. The memory device is connected to a host, such as a computer or card reader, through an interface circuit, to enable the host to retrieve data or program from the flash memory. The single chip flash memory controller prohibits the host to store or write data into the write-protected block(s) according to the preset write-protect parameter. Accordingly, the present invention do not require altering of the hardware structure or circuit connection of the memory device, but rather merely proposes to set up the write-protect parameter into the single chip flash memory controller to mark any block for substantially protecting the data or program therein.
