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 x18 need to add 276mA for the

following: VDD = 2.5V, VTERM = 1.8V, VREF = 1.4V and VDIL = VREF

− 0.5V.
