+        help
+          The 2X Program is an extension of Program Operation.
+          Since the device is equipped with two DataRAMs, and two-plane NAND
+          Flash memory array, these two component enables simultaneous program
+          of 4KiB. Plane1 has only even blocks such as block0, block2, block4
+          while Plane2 has only odd blocks such as block1, block3, block5.
+          So MTD regards it as 4KiB page size and 256KiB block size
+
+          Now the following chips support it. (KFXXX16Q2M)
+            Demux: KFG2G16Q2M, KFH4G16Q2M, KFW8G16Q2M,
+            Mux:   KFM2G16Q2M, KFN4G16Q2M,
+
+          And more recent chips
