12. About Burst Type Control

Basic

MODE

Random

MODE

Sequential counting

Interleave counting

Random column Access

tCCD = 1 CLK

At MRS A3=”0”. See the BURST SEQUENCE TABE.(BL=4,8)

BL=1,2,4,8 and full page wrap around.

At MRS A3=” 1”. See the BURST SEQUENCE TABE.(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 convention DRAM.

13. About Burst Length Control

MODE

1

At MRS A2,1,0 = “000”.

At auto precharge, tRAS should not be violated.

2

At MRS A2,1,0 = “001”.

At auto precharge, tRAS should not be violated.

4

At MRS A2,1,0 = “010”

8

At MRS A2,1,0 = “011”.

At MRS A9=”1”.

BRSW

Read burst = 1,2,4,8, full page/write Burst =1

At auto precharge of write, tRAS should not be violated.

Before the end of burst, Row precharge command of the same bank

RAS Interrupt

Stops read/write burst with Row precharge.

(Interrupted by Precharge) tRDL=1 with DQM, valid DQ after burst stop is 1,2 for CL=2,3 respectively

During read/write burst with auto precharge, RAS interrupt cannot be issued.

Before the end of burst, new read/write stops read/write burst and starts new

CAS Interrupt

read/write burst or block write.

During read/write burst with auto precharge, CAS interrupt can not be issued.
