SIGNAL DESCRIPTIONS
See
Names, for a brief overview of the signals connect-
ed to this device.
Address Inputs (A0-A19). The Address Inputs
select the cells in the memory array to access dur-
ing Bus Read operations. During Bus Write opera-
tions they control the commands sent to the
Command Interface of the internal state machine.
Data Input/Output (DQ0-DQ15). The Data I/O
outputs the data stored at the selected address
during a Bus Read operation or inputs a command
or the data to be programmed during a Write Bus
operation.
Chip Enable (E). The Chip Enable input acti-
vates the memory control logic, input buffers, de-
coders and sense amplifiers. When Chip Enable is
at V
mode. When Chip Enable is at V
deselected, the outputs are high impedance and
the power consumption is reduced to the stand-by
level.
Output Enable (G). The Output Enable controls
data outputs during the Bus Read operation of the
memory.
Write Enable (W). The Write Enable controls the
Bus Write operation of the memory’s Command
Interface. The data and address inputs are latched
on the rising edge of Chip Enable, E, or Write En-
able, W, whichever occurs first.
Write Protect (WP). Write Protect is an input
that gives an additional hardware protection for
each block. When Write Protect is at V
Down is enabled and the protection status of the
block cannot be changed. When Write Protect is at

be locked or unlocked. (refer to
Protection Register and Lock
Reset (RP). The Reset input provides a hard-
ware reset of the memory. When Reset is at V
the memory is in reset mode: the outputs are high
impedance and the current consumption is mini-
mized. After Reset all blocks are in the Locked

read array mode, but a negative transition of Chip

ensure valid data outputs.
