Sector Erase Suspend / Resume Commands
This command suspends automatic erase. During erase
suspend, sectors for which erase is not performed can be read
and programmed.
Sector erase (including the timeout period) and data program
operations can be both be suspended. Chip erase operations
cannot be suspended. Suspend can be performed for all
sectors for which erase is being performed.
Following command sequence write, 20
μ
s are required until
automatic erase is suspended.
While automatic erase is suspended, any sector for which
erase is not being performed can be read and programmed.
Whether automatic erase is suspended can be determined
with the hardware sequence flags (I/O
7
, I/O
6
, I/O
2
pins). See
sections “I/O7 (Data Polling)”, “I/O6 (Toggle Bit)”, and “I/O2
(Toggle Bit II)".
If resume automatic erase that has been suspended, write the
resume command (30H) while sector erase is suspended. At
this time, input a bank address of the sector for which erasure
is suspended.
Caution Sector Erase Suspend / Resume Commands
If automatic erase resume and suspend are repeated at
intervals of less than 100
μ
s, the erasure operation may not be
correctly completed.
Unlock Bypass Command Sequence
This device provides an unlock bypass mode to shorten the
program time.
Normally, 4 write cycle included with 2 unlock cycles are
required during program. In contrast, with the unlock bypass
mode, it is possible to perform program without unlock cycles.
In the unlock bypass mode, all commands except unlock
bypass program and unlock bypass reset are ignored.
To end the unlock bypass mode, the unlock bypass reset
command must be written. Note, however, that the unlock
bypass reset command must be written to an address of the
bank that is not being read in dual operation. If the unlock
bypass reset command is written, the device returns to the
normal read mode.
In the unlock bypass mode, the operating current is necessary
even if
CE
= V
IH
.
For the flowchart, refer to Figure 5.
Unlock Bypass Set
This command sets the device to the unlock bypass mode.
Unlock Bypass Program
This command is used to perform program in the unlock
bypass mode.
Unlock Bypass Reset
This command is used to quit the unlock bypass mode.
When this command is executed, the device returns to the
read mode.
