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 CAS 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.
