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 4 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.
Table4. Read Staus Register Definition
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.
I/O No.
