Write Operation Status
Data Polling—DQ7
The device features Data# Polling as a method to indi-
cate to the host system that the Embedded algorithms
are either in progress or completed.
While the Embedded Programming algorithm is in oper-
ation, an attempt to read the device at a valid address
will produce the complement of expected Valid data on
DQ7. Upon completion of the Embedded Program algo-
rithm an attempt to read the device at a valid address will
produce Valid data on DQ7. The Data# Polling feature is
valid after the rising edge of the second WE# pulse of
the two write pulse sequence.
While the Embedded Erase algorithm is in operation,
DQ7 will read “0"
until the erase operation is com-
pleted. Upon completion of the erase operation, the
data on DQ7 will read “1.” The Data# Polling feature is
valid after the rising edge of the second WE# pulse of
the two Write pulse sequence.
The Data# Polling feature is only active during Embed-
ded Programming or erase algorithms.
See Figures 3 and 4 for the Data# Polling timing spec-
ifications and diagrams. Data# Polling is the standard
method to check the write operation status, however,
an alternative method is available using Toggle Bit.

Note:
DQ7 is rechecked even if DQ5 = “1” because DQ7 may change simultaneously with DQ5 or after DQ5.
