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.
At MRS A2,1,0 = “000”.
At auto precharge, tRAS should not be violated.

Read burst = 1,2,4,8, FP 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
Stops read/write burst with Row precharge.
t
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
read/write burst or block write.
During read/write burst with auto precharge,
