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 oper-
ations. Table 34 and Table 35 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 ad-
dresses are no longer latched. The system can determine the status of the erase operation by
using DQ7, DQ6, or DQ2. See Write Operation Status for information on these status bits.
Any commands written during the chip erase operation are ignored. However, note that a hard-
ware reset immediately terminates the erase operation. If that occurs, the chip erase command
sequence should be reinitiated once the device returns to reading array data, to ensure data
integrity.
Figure 6 illustrates the algorithm for the erase operation. See Erase and Programming Perfor-
mance in AC Characteristics for parameters, and Figure 18 for timing diagrams.
Sector Erase Command Sequence
Sector erase is a six bus cycle operation. The sector erase command sequence is initiated by writ-
ing two unlock cycles, followed by a set-up command. Two additional unlock cycles are written,
and are then followed by the address of the sector to be erased, and the sector erase command.
Table 34 and Table 35 shows the address and data requirements for the sector erase command
sequence.
