Preliminary
Restriction in addressing with Multi Plane Page Program
While any block in each plane may be addressable for Multi-Plane Page Program, the five least significant addresses(A9-A13) for
the selected pages at one operation must be the same. Figure 14 shows an example where 2nd page of each addressed block is
selected for four planes. However, any arbitrary sequence is allowed in addressing multiple planes as shown in Figure15.

Multi-Plane Block Erase into Plane 0~3 or Plane 4~7
Basic concept of Multi-Plane Block Erase operation is identical to that of Multi-Plane Page Program. Up to four blocks, one from each
plane can be simultaneously erased. Standard Block Erase command sequences (Block Erase Setup command followed by three
address cycles) may be repeated up to four times for erasing up to four blocks. Only one block should be selected from each plane.
The Erase Confirm command initiates the actual erasing process. The completion is detected by analyzing R/B pin or Ready/Busy
status (I/O 6). Upon the erase completion, pass/fail status of each block is examined by reading extended pass/fail status(I/O 1
through I/O 4).
