System Interface Using CE don’t care
To simplify system interface, CE may be deasserted during data loading or sequential data-reading as shown below. So, it is possible
to connect NAND Flash to a microprocessor. The only function that was removed from standard NAND Flash to make CE don't care
read operation was disabling of the automatic sequential read function.
