Full-page Burst Stop
Burst stop command during burst read:
The burst stop (BST) command is used to stop data output during
a full-page burst. The BST command sets the output buffer to High-Z and stops the full-page burst read. The
timing from command input to the last data changes depending on the
CE
latency setting. In addition, the
BST command is valid only during full-page burst mode, and is illegal with burst lengths 1, 2, 4 and 8.

Burst stop command at burst write:
The burst stop command (BST command) is used to stop data input
during a full-page burst write. No data is written in the same clock as the BST command, and in subsequent
clocks. In addition, the BST command is only valid during full-page burst mode, and is illegal with burst
lengths of 1, 2, 4 and 8. And an interval of t
DPL
is required between last data-in and the next precharge
command.
