Write Operation Status

The device provides several bits to determine the status of a program or erase operation. The following subsections describe the
function of DQ1, DQ2, DQ3, DQ5, DQ6, and DQ7.

7.8.1

DQ7: Data# Polling

The Data# Polling bit, DQ7, indicates to the host system whether an Embedded Program or Erase algorithm is in progress or
completed, or whether the device is in Erase Suspend. Data# Polling is valid after the rising edge of the final WE# pulse in the
command sequence. Note that the Data# Polling is valid only for the last word being programmed in the write-buffer-page during
Write Buffer Programming. Reading Data# Polling status on any word other than the last word to be programmed in the write-buffer-
page returns false status information.

During the Embedded Program algorithm, the device outputs on DQ7 the complement of the datum programmed to DQ7. This DQ7
status also applies to programming during Erase Suspend. When the Embedded Program algorithm is complete, the device outputs
the datum programmed to DQ7. The system must provide the program address to read valid status information on DQ7. If a program
address falls within a protected sector, Data# polling on DQ7 is active, then that sector returns to the read mode.

During the Embedded Erase Algorithm, Data# polling produces a “0” on DQ7. When the Embedded Erase algorithm is complete, or
if the device enters the Erase Suspend mode, Data# Polling produces a “1” on DQ7. The system must provide an address within any
of the sectors selected for erasure to read valid status information on DQ7.

After an erase command sequence is written, if all sectors selected for erasing are protected, Data# Polling on DQ7 is active for
approximately 100



µs, then the device returns to the read mode. If not all selected sectors are protected, the Embedded Erase

algorithm erases the unprotected sectors, and ignores the selected sectors that are protected. However, if the system reads DQ7 at
an address within a protected sector, the status may not be valid.
