access is allowed. Internal WRITE to READ command interval(tWTR) is minimum 1 CLK. The
input data on DQ at the interrupting READ cycle is "don't care". tWTR is referenced from the first
positive edge after the last data input.
Burst write operation can be interrupted by write of any bank. Random column access is allowed.
WRITE to WRITE interval is minimum 1 CLK.
Burst write operation can be interrupted by read of the same or the other bank. Random column
