[ Read with Auto-Precharge Interrupted by Read to another Bank ]
Burst read with auto-precharge can be interrupted by read to
another
bank. Next ACT comand can
be issued after (BL+tRP) from the READA. Auto-precharge interruption by a command to the same
bank is inhibited.

Full Page Burst
Full page burst length is available for only the sequential burst type. Full page burst read / write is
repeated untill a Precharge or a Burst Terminate command is issued. In case of the full page burst,
a read / write with auto-precharge command is illegal.
Single Write
When sigle write mode is set, burst length for write is always one, independently of Burst Length
defined by (A2-0).
