• Manufacturer Part Number: MX26LV800T
• Description: 8M-Bit CMOS Single Voltage Flash Memory
• Manufacturer: Macronix

TABLE 6. SILICON ID CODE
READING ARRAY DATA
The device is automatically set to reading array data
after device power-up. No commands are required to re-
trieve data. The device is also ready to read array data
after completing an Automatic Program or Automatic
Erase algorithm.
The system must issue the reset command to re-en-
able the device for reading array data if Q5 goes high, or
while in the autoselect mode. See the "Reset Command"
section, next.

RESET COMMAND
Writing the reset command to the device resets the de-
vice to reading array data. Address bits are don't care
for this command.
The reset command may be written between the se-
quence cycles in an erase command sequence before
erasing begins. This resets the device to reading array
data. Once erasure begins, however, the device ignores
reset commands until the operation is complete.
The reset command may be written between the se-
quence cycles in a program command sequence before
programming begins. This resets the device to reading
array data. Once programming begins, however, the de-
vice ignores reset commands until the operation is com-
plete.
The reset command may be written between the se-
quence cycles in an SILICON ID READ command se-
quence. Once in the SILICON ID READ mode, the reset
command must be written to return to reading array data.
If Q5 goes high during a program or erase operation,
writing the reset command returns the device to read-
ing array data.
