Flash memory Inputs/Outputs (I/O0-I/O7)
Input/Outputs 0 to 7 are used by the NAND Flash memory 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 NAND Flash memory is deselected or the outputs are disabled.
Flash memory Inputs/Outputs (I/O8-I/O15)
Input/Outputs 8 to 15 are only available in x16 NAND Flash 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.
Flash memory Address Latch Enable (AL)
The Address Latch Enable activates the latching of the Address inputs in the Command
Interface of the NAND Flash memory. When AL is high, the inputs are latched on the rising
edge of Write Enable.
Flash memory Command Latch Enable (CL)
The Command Latch Enable activates the latching of the Command inputs in the Command
Interface of the NAND Flash memory. When CL is high, the inputs are latched on the rising
edge of Write Enable.
Flash memory Chip Enable (E
The NAND Flash memory Chip Enable input activates the memory control logic, input
buffers, decoders and sense amplifiers. When Chip Enable is low, V
memory device is selected. If Chip Enable goes high, v
busy, the device remains selected and does not go into standby mode.
