Address latch enable: During the time ALE is HIGH, address information is
transferred from I/O[7:0] into the on-chip address register upon a LOW to HIGH
transition on WE#
should be driven LOW.
Chip enable: Gates transfers between the host system and the NAND device. Once
the device starts a PROGRAM or ERASE operation, the chip enable pin can be de-
asserted. For the 8Gb configuration, CE# controls the first 4Gb of memory; CE2#
controls the second 4Gb. See the Bus Operation section, starting on page 16, for
additional operational details.
Command latch enable: When CLE is HIGH, information is transferred from
I/O[7:0] to the on-chip command register on the rising edge of WE#. When
command information is not being loaded, the CLE pin should be driven LOW.
Power-on read enable: Enables the auto-read function when at Vcc. See the bus
operation section, starting on page 16, for additional details.
Read enable: Gates transfers from the NAND device to the host system.
Write enable: Gates transfers from the host system to the NAND device.
Write protect: Pin protects against inadvertent PROGRAM and ERASE operations.
All PROGRAM and ERASE operations are disabled when the WP# pin is LOW.
Data inputs/outputs: The bidirectional I/O pins transfer address, data, and
instruction information. Data is output only during READ operations; at other
times the I/O pins are inputs.
Ready/busy: An open-drain, active-LOW output, that uses an external pull-up
resistor. The pin is used to indicate when the chip is processing a PROGRAM or
ERASE operation. The pin is also used during a READ operation to indicate when
data is being transferred from the array into the serial data register. Once these
operations have completed, the R/B# returns to the high-impedance state. In the
8Gb configuration, R/B# is for the 4Gb of memory enabled by CE#; R/B2# is for the
4Gb of memory enabled by CE2#.
