MULTI-PLANE BLOCK ERASE
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).

READ STATUS
The device contains a Status Register which may be read to find out whether program or erase operation is completed, and whether
the program or erase operation is completed successfully. After writing 70h command to the command register, a read cycle outputs
the content of the Status Register to the I/O pins on the falling edge of CE or RE, whichever occurs last. This two line control allows
the system to poll the progress of each device in multiple memory connections even when R/B pins are common-wired. RE or CE
does not need to be toggled for updated status. Refer to table 2 for specific Status Register definitions. The command register
remains in Status Read mode until further commands are issued to it. Therefore, if the status register is read during a random read
cycle, a read command(00h or 50h) should be given before sequential page read cycle.
For Read Status of Multi Plane Program/Erase, the Read Multi-Plane Status command(71h) should be used to find out whether
multi-plane program or erase operation is completed, and whether the program or erase operation is completed successfully. The
pass/fail status data must be checked only in the Ready condition after the completion of Multi-Plane program or erase operation.

NOTE
:
1. I/O 0 describes combined Pass/Fail condition for all planes. If any of the selected multiple pages/blocks fails in Program/
Erase operation, it sets "Fail" flag.
2. The pass/fail status applies only to the corresponding plane.
