connected to this device. The NAND08G-B4C devices have two separate sets of signals for
each 4 Gb die.
Inputs/outputs (I/O0-I/O7)
Input/outputs 0 to 7 input the selected address, output the data during a read operation, or
input a command or data during a write operation. The inputs are latched on the rising edge
of Write Enable. I/O0-I/O7 are left floating when the device is deselected or the outputs are
disabled.
Inputs/Outputs (I/O8-I/O15)
Input/Outputs 8 to 15 are only available in x16 devices. They output the data during a read
operation or input data during a write operation. Command and address inputs only require
I/O0 to I/O7.
The inputs are latched on the rising edge of Write Enable. I/O8-I/O15 are left floating when
the device is deselected or the outputs are disabled.
Address Latch Enable (AL)
The Address Latch Enable activates the latching of the address inputs in the Command
Interface. When AL is high, the inputs are latched on the rising edge of Write Enable.
Command Latch Enable (CL)
The Command Latch Enable activates the latching of the command inputs in the Command
Interface. When CL is high, the inputs are latched on the rising edge of Write Enable.
Chip Enable (E)
The Chip Enable input, E, activates the memory control logic, input buffers, decoders and
sense amplifiers. When Chip Enable is low, V
high, V

Read Enable (R)
The Read Enable pin, R, controls the sequential data output during read operations. Data is
