provides the detailed descriptions of the signals.
Input/outputs 0 to 7 are used to 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.
Input/outputs 8 to 15 are only available in x16 devices.
They are used to 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.
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.
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.
The Chip Enable input activates the memory control logic,
input buffers, decoders and read circuitry. When Chip
Enable is Low, V
