7.11 Data Polling Algorithm
START
Read DQ7-DQ0
Addr=VA
DQ7=Data?
No
DQ5=1?
Yes
No
DQ7=Data?
Read DQ7-DQ0
Addr=VA
FAIL
PASS
Yes
No
Notes:
1. VA = Valid address for programming. During a sector erase operation; a valid address is any sector address within the
sector being erased. During chip erase, a valid address is any non-protected sector address.
2. DQ7 should be rechecked even if DQ5 = “1” because DQ7 may change simultaneously with DQ5.
