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 5, 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, V
and Output Enable and keeping Write Enable
High, V
value, see Figure 8, Read Mode AC Waveforms,
and Table 12, 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, V
Write operation. See Figures 9 and 10, Write AC
Waveforms, and Tables 13 and 14, Write AC
Characteristics, for details of the timing require-
ments.
Output Disable. The Data Inputs/Outputs are in
the high impedance state when Output Enable is
High, V

Standby. When Chip Enable is High, V
Inputs/Outputs pins are placed in the high-imped-
ance state and the Supply Current is reduced to the
Standby level.

Automatic Standby. If CMOS levels (V
are used to drive the bus and the bus is inactive for
150ns or more the memory enters Automatic Stand-

the CMOS Standby Supply Current, I
Inputs/Outputs will still output data if a Bus Read op-
eration is in progress.
Special Bus Operations
Additional bus operations can be performed to read
the Electronic Signature and also to apply and re-
move Block Protection. These bus operations are
intended for use by programming equipment and
are not usually used in applications. They require
