Reading Array Data
Writing specific address and data commands or sequences into the command register initiates device
operations.
address and data values or writing them in the improper sequence may place the device in an unknown
state. A reset command is then required to return the device to reading array data.
All addresses are latched on the falling edge of WE# or CE# (CE1# / CE2# in PL129J), whichever happens
later. All data is latched on the rising edge of WE# or CE# (CE1# / CE2# in PL129J), whichever happens first.
Refer to
The device is automatically set to reading array data after device power-up. No commands are required to
retrieve data. Each bank is ready to read array data after completing an Embedded Program or Embedded
Erase algorithm.
After the device accepts an Erase Suspend command, the corresponding bank enters the erase-suspend-
read mode, after which the system can read data from any non-erase-suspended sector within the same
bank. The system can read array data using the standard read timing, except that if it reads at an address
within erase-suspended sectors, the device outputs status data. After completing a programming operation in
the Erase Suspend mode, the system may once again read array data with the same exception. See
Suspend/Erase Resume Commands on page 60
After the device accepts a Program Suspend command, the corresponding bank enters the program-
suspend-read mode, after which the system can read data from any non-program-suspended sector within
the same bank. See
The system must issue the reset command to return a bank to the read (or erase-suspend-read) mode if DQ5
goes high during an active program or erase operation, or if the bank is in the autoselect mode. See the next
section,
