BUS OPERATIONS
There are five standard bus operations that control
the device. These are Bus Read, Bus Write, Out-
put Disable, Standby and Automatic Standby. See
Table 2, Bus Operations, for a summary. Typically
glitches of less than 5ns on Chip Enable or Write
Enable are ignored by the memory and do not af-
fect bus operations.
Bus Read. Bus Read operations read from the
memory cells, or specific registers in the Com-
mand Interface. A valid Bus Read operation in-
volves setting the desired address on the Address
Inputs, applying a Low signal, VIL, to Chip Enable
and Output Enable and keeping Write Enable
High, VIH. The Data Inputs/Outputs will output the
value, see Figure 9, Read Mode AC Waveforms,
and Table 10, Read AC Characteristics, for details
of when the output becomes valid.
Bus Write. Bus Write operations write to the
Command Interface. A valid Bus Write operation
begins by setting the desired address on the Ad-
dress Inputs. The Address Inputs are latched by
the Command Interface on the falling edge of Chip
Enable or Write Enable, whichever occurs last.
The Data Inputs/Outputs are latched by the Com-
mand Interface on the rising edge of Chip Enable
or Write Enable, whichever occurs first. Output En-
able must remain High, VIH, during the whole Bus
Write operation. See Figure 10 and Figure 11,
Write AC Waveforms, and Table 11 and Table 12,
Write AC Characteristics, for details of the timing
requirements.
Output Disable. The Data Inputs/Outputs are in
the high impedance state when Output Enable is
High, VIH.
Standby. When Chip Enable is High, VIH, the
memory enters Standby mode and the Data In-
puts/Outputs pins are placed in the high-imped-
ance state. To reduce the Supply Current to the
Standby Supply Current, ICC2, Chip Enable should
be held within VCC ± 0.2V. For the Standby current
level see Table 9, DC Characteristics.
During program or erase operations the memory
will continue to use the Program/Erase Supply
Current, ICC3, for Program or Erase operations un-
til the operation completes.
Automatic Standby. If CMOS levels (VCC ± 0.2V)
are used to drive the bus and the bus is inactive for
300ns or more the memory enters Automatic
Standby where the internal Supply Current is re-
duced to the Standby Supply Current, ICC2. The
Data Inputs/Outputs will still output data if a Bus
Read operation is in progress.
Special Bus Operations
Additional bus operations can be performed to
read the Electronic Signature and also to apply
and remove Block Protection. These bus opera-
tions are intended for use by programming equip-
ment and are not usually used in applications.
They require VID to be applied to some pins.
Electronic Signature. The
memory
has
two
codes, the manufacturer code and the device
code, that can be read to identify the memory.
These codes can be read by applying the signals
listed in Table 2, Bus Operations.
Block Protect and Chip Unprotect. Groups
of
blocks can be protected against accidental Pro-
gram or Erase. The whole chip can be unprotected
to allow the data inside the blocks to be changed.
Write Protect (WP) can be used to protect one of
the outermost blocks. When Write Protect (WP) is
at VIL one of the two outermost blocks is protect-
ed and remains protected regardless of the Block
Protection Status or the Reset/Block Temporary
Unprotect pin status. For the M29W641DH, it is
the highest addressed block that can be protect-
ed. For the M29W641DL, it is the lowest.
Block Protect and Chip Unprotect operations are
described in Appendix D.
