be undefined. In that case, restart the erase on that
sector and allow it to complete.
The automatic sector erase begins after the 100
μ
s
time out from the rising edge of the WE# (or CE#)
pulse for the last sector erase command pulse and
terminates when the data on D7 is “1” (see Write
Operation Status section) at which time the device
returns to read mode. Data Polling must be per-
formed at an address within any of the sectors being
erased.
Figure 4 illustrates the Embedded Erase Algorithm
using typical command strings and bus operations.

Embedded Program Algorithm
The Embedded Program setup is a four bus cycle oper-
ation that stages the addressed memory sector or
memory device for automatic programming.
Once the Embedded Program setup operation is per-
formed, the next WE
#
(or CE#) pulse causes a transi-
tion to an active programming operation. Addresses
are internally latched on the falling edge of the WE
#
(or
CE#) pulse. Data is internally latched on the rising
edge of the WE
#
pulse. The rising edge of WE
#
also
begins the programming operation. The system is not
required to provide further control or timing. The device
will automatically provide an adequate internally gener-
ated write pulse and verify margin. The automatic pro-
gramming operation is completed when the data on D7
of the addressed memory sector or memory device is
equivalent to data written to this bit (see Write Opera-
tion Status section) at which time the device returns to
the Read mode (no write verify command is required).
Addresses are latched on the falling edge of WE
#
during the Embedded Program command execution
and hence the system is not required to keep the
addresses stable during the entire Programming oper-
ation. However, once the device completes the
Embedded Program operation, it returns to the Read
mode and addresses are no longer latched. Therefore,
the device requires that a valid address input to the
device is supplied by the system at this particular
instant of time. Otherwise, the system will never read a
valid data on D7. A system designer has two choices to
implement the Embedded Programming algorithm:
1. The system (CPU) keeps the address valid during
the entire Embedded Programming operation, or
2. Once the system executes the Embedded Program-
ming command sequence, the CPU takes away the
address from the device and becomes free to do
other tasks. In this case, the CPU is required to
keep track of the valid address by loading it into a
temporary register. When the CPU comes back for
performing Data Polling, it should reassert
the same address.
3. The host may monitor BUSY# (RY/BY#) to deter-
mine the status of the Embedded Algorithm in
progress. A “0” indicates that the device is busy; a
“1” indicates that the algorithm is complete.
However, since the Embedded Programming operation
takes only 8
μ
s typically, it may be easier for the CPU
to keep the address stable during the entire Embedded
Programming operation instead of reasserting the valid
address during Data Polling. Anyway, this has been left
to the system designer’s choice to go for either opera-
tion. Any commands written to the device during this
period will be ignored. Figure 5 and Table 14 illustrate
the Embedded Program Algorithm, a typical command
string, and bus operation.
