The device has a R/B output that provides a hardware method of indicating the completion of a page program, erase and random read completion. The R/B pin is normally high but transitions to low after program or erase command is written to the command reg- ister or random read is started after address loading. It returns to high when the internal controller has finished the operation. The pLn is an open-drain driver thereby allowing two or more R/B outputs to be Or-tied. Because pull-up resistor value is related to tr(R/B) and current drain during busy(ibusy) , an appropriate value can be obtained with the following reference chart(Fig 16). Its value can be determined by the following guidance.
