12. About Burst Type Control
At MRS A
3
= "0". See the BURST SEQUENCE TABLE. (BL=4, 8)
BL=1, 2, 4, 8 and full page.
At MRS A
3
= "1". See the BURST SEQUENCE TABLE. (BL=4, 8)
BL=4, 8. At BL=1, 2 Interleave Counting = Sequential Counting
Every cycle Read/Write Command with random column address can realize Random
Column Access.
That is similar to Extended Data Out (EDO) Operation of conventional DRAM.

13. About Burst Length Control
At MRS A
2,1,0
= "000".
At auto precharge, t
RAS
should not be violated.
At MRS A
2,1,0
= "001".
At auto precharge, t
RAS
should not be violated.
Before the end of burst, Row precharge command of the same bank stops read/write
burst with Row precharge.
t
RDL
= 1 with DQM, valid DQ after burst stop is 1, 2 for CAS latency 2, 3 respectively.
During read/write burst with auto precharge, RAS interrupt can not be issued.

At MRS A

At MRS A
2,1,0

Wrap around mode(infinite burst length) should be stopped by burst stop.
RAS interrupt or CAS interrupt

At auto precharge of write, t
RAS

BDL
= 1, Valid DQ after burst stop is 1, 2 for CAS latency 2, 3 respectively
Using burst stop command, any burst length control is possible.

Before the end of burst, new read/write stops read/write burst and starts new
read/write burst.
During read/write burst with auto precharge, CAS interrupt can not be issued.
