BUS OPERATIONS
There are five standard busoperations that control
the device. These are Bus Read, Bus Write, Out-
put Disable, Standby and Automatic Standby. See
Tables 4A and 4B, Bus Operations, for a summa-
ry. Typically glitches of less than 5ns on Chip En-
able or Write Enable are ignored by the memory
and do not affect 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
IL
, to Chip Enable
and Output Enable and keeping Write Enable
High, V
IH
. The Data Inputs/Outputs will output the
value, see Figure 7, Read Mode AC Waveforms,
and Table 11, 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 WriteEnable, whichever occurs first.OutputEn-
able must remain High, V
IH
, during the whole Bus
Write operation. See Figures 8 and 9, Write AC
Waveforms, and Tables 12 and 13, 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
IH
.
