Hi, I am looking for the impedance requirement in PCB layout of SDRAM MT41K256M16 by Micron. I have looked at the datasheet but I am not sure if I am looking at the right sections or not. On page 62 it says output driver impedance 40 Ohm. I am wondering if it applies to all DQ[0:15], ADR[0:13], BA[0:2], and other signals or maybe not.
