Chip Erase Command Sequence
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. Table 10.2 on page 61 and Table 10.1 on page 62 show the
address and data requirements for the chip erase command sequence.
When the Embedded Erase algorithm is complete, the device returns to the read mode and addresses are no
longer latched. The system can determine the status of the erase operation by using DQ7, DQ6, or DQ2.
Refer to Write Operation Status on page 63 for information on these status bits.
Any commands written during the chip erase operation are ignored. However, note that a hardware reset
immediately terminates the erase operation. If this occurs, the chip erase command sequence should be
reinitiated once the device returns to reading array data, to ensure data integrity.
Figure 10.1 on page 59 illustrates the algorithm for the erase operation. Refer to Table 16.5 on page 76 for
parameters, and Figure 16.7 on page 80 for timing diagrams.
