quence should be reinitiated once the device has reset
to reading array data, to ensure data integrity.
Programming is allowed in any sequence and across
sector boundaries.
A bit cannot be programmed
from a “0” back to a “1”.
Attempting to do so may halt
the operation and set DQ5 to “1,” or cause the Data#
Polling algorithm to indicate the operation was suc-
cessful. However, a succeeding read will show that the
data is still “0”. Only erase operations can convert a “0”
to a “1”.
Unlock Bypass Command Sequence
The unlock bypass feature allows the system to pro-
gram bytes to the device faster than using the standard
program command sequence. The unlock bypass com-
mand sequence is initiated by first writing two unlock
cycles. This is followed by a third write cycle containing
the unlock bypass command, 20h. The device then en-
ters the unlock bypass mode. A two-cycle unlock by-
pass program command sequence is all that is
required to program in this mode. The first cycle in this
sequence contains the unlock bypass program com-
mand, A0h; the second cycle contains the program ad-
dress and data. Additional data is programmed in the
same manner. This mode dispenses with the initial two
unlock cycles required in the standard program com-
mand sequence, resulting in faster total programming
time. Table 9 shows the requirements for the command
sequence.
During the unlock bypass mode, only the Unlock By-
pass Program and Unlock Bypass Reset commands
are valid. To exit the unlock bypass mode, the system
must issue the two-cycle unlock bypass reset com-
mand sequence. The first cycle must contain the data
90h; the second cycle the data 00h. Addresses are
don’t cares for both cycles. The device then returns to
reading array data.
Figure 3 illustrates the algorithm for the program oper-
ation. See the Erase/Program Operations table in “AC
Characteristics” for parameters, and to Figure 15 for
timing diagrams
Note:
See Table 9 for program command sequence.
