256M Double Data Rate Synchronous DRAM
Burst write operation can be interrupted by Write to any bank. Random column access is allowed. WRITE
to WRITE interval is 1 CLK minimum.
[Write interrupted by Write]
[Write interrupted by Read]
Burst write operation can be interrupted by read of the same or the other bank. Random column access is
allowed. Internal WRITE to READ command interval(tWTR) is 1 CLK minimum. The input data masked by
DM in the interrupted READ cycle is "don't care". tWTR is referenced from the first positive edge after the last
data input.
