Diagrams and Pin/Pad Connections of NAND

Figure 4883 shows a dual plane device of a NAND chip:

  • Wordline decoder -- Is in the middle of the two planes (in some devices there could be one row decoder per plane).
  • Column decoder (bitline decoder) -- Is at the bottom.
  • Wordlines -- Is in the horizontal direction.
  • Bitlines -- Is in the vertical direction.
  • Block -- Is made up by a group of wordlines (typically 32 or 64).
