  14           This adds an extra check when data is written to the flash. The
  15           OneNAND flash device internally checks only bits transitioning
  16           from 1 to 0. There is a rare possibility that even though the
  17           device thinks the write was successful, a bit could have been
  18           flipped accidentally due to device wear or something else.

  44           One Block of the NAND Flash Array memory is reserved as
  45           a One-Time Programmable Block memory area.
  46           Also, 1st Block of NAND Flash Array can be used as OTP.
  47
  48           The OTP block can be read, programmed and locked using the same
  49           operations as any other NAND Flash Array memory block.
  50           OTP block cannot be erased.
  51
  52           OTP block is fully-guaranteed to be a valid block.

  57           The 2X Program is an extension of Program Operation.
  58           Since the device is equipped with two DataRAMs, and two-plane NAND
  59           Flash memory array, these two component enables simultaneous program
  60           of 4KiB. Plane1 has only even blocks such as block0, block2, block4
  61           while Plane2 has only odd blocks such as block1, block3, block5.
  62           So MTD regards it as 4KiB page size and 256KiB block size
  63
  64           Now the following chips support it. (KFXXX16Q2M)
  65             Demux: KFG2G16Q2M, KFH4G16Q2M, KFW8G16Q2M,
