Notes 1. Actual power will depend on individual RDRAM component specifications, memory controller and usage
patterns. Power does not include Refresh Current.
2. I/O current is a function of the % of 1’s, to add I/O power for 50 % 1’s for a x16 need to add 257 mA or 290
mA for x18 ECC module for the following : VDD = 2.5 V, VTERM = 1.8 V, VREF = 1.4 V and VDIL = VREF − 0.5 V.
