Chip Erase Command Sequence
Note
See
Chip erase is a six bus cycle operation. The chip erase command sequence is initiated by writing two unlock
cycles, followed by a set-up command. Two additional unlock write cycles are then followed by the chip erase
command, which in turn invokes the Embedded Erase algorithm. The device does not require the system to
preprogram prior to erase. The Embedded Erase algorithm automatically preprograms and verifies the entire
memory for an all zero data pattern prior to electrical erase. The system is not required to provide any
controls or timings during these operations.
for the chip erase command sequence.
Any commands written to the chip during the Embedded Erase algorithm are ignored. Note that a hardware
reset during the chip erase operation immediately terminates the operation. The Chip Erase command
sequence should be reinitiated once the device has returned to reading array data, to ensure data integrity.
The system can determine the status of the erase operation by using DQ7, DQ6, DQ2, or RY/BY#. See
