Burst Sequence
Full page burst is available only for sequential addressing. The addressing sequence is started from the column
address that is asserted by read/write command. And the address is increased one by one.
It is back to the address 0 when the address reaches at the end of address 511. “Full page burst” stops the burst
read/write with burst stop command.
