and Chip Enable remains Low, then the next page is automatically loaded into the page
buffer and the read operation continues. A sequential row read operation can only be
used to read within a block. If the block changes a new read command must be issued.
block diagrams for details about sequential row read operations. To terminate a
sequential row read operation, set to High the Chip Enable signal for more than tEHEL.
Sequential row read is not available when the Chip Enable don’t care option is enabled.
