This structure describes standard information for a particular flash region. FLASH_REGION_INFO is the output structure for IOCTL_FLASH_PDD_GET_REGION_INFO.

Syntax

typedef struct __FLASH_REGION_INFO {
  ULONG FlashFlags;
  ULONGLONG StartBlock;
  ULONGLONG BlockCount;
  ULONG SectorsPerBlock;
  ULONG DataBytesPerSector;
  ULONG SpareBytesPerSector;
  ULONG PageProgramLimit;
  ULONG BadBlockHundredthPercent
} FLASH_REGION_INFO;

Members

  • FlashFlags
    Indicates the features supported for this flash part.
  • StartBlock
    The starting physical block for the flash hardware region.
  • BlockCount
    The total number of physical blocks in the flash region.
  • SectorsPerBlock
    The number of sectors in a block.
  • DataBytesPerSector
    The number of data bytes in a sector.
  • SpareBytesPerSector
    The number of spare bytes in a sector available for use by the model device driver (MDD).
  • PageProgramLimit
    The number of program operations allowed per page. This value can be 1.
  • BadBlockHundredthPercent
    The percentage of blocks that are expected to go bad during the lifetime of the flash part. This value is expressed as 1/100th of one percent units. For example, if 1% of blocks were expected to go bad during the lifetime of the flash part, this value would be 100.
