Notes 1. Actual power will depend on individual RDRAM component specifications, memory controller and usage
patterns. Please refer to specific RIMM module vendor data sheets for additional information. Power does
not include Refresh Current. Max current computed for x16 256Mb RDRAM components. x18 288Mb
RDRAM components use 8 mA more current per RDRAM device in Read and 60mA more current per
RDRAM device in Write.
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 257mA for the
following : VDD = 2.5V, VTERM = 1.8V, VREF = 1.4V and VDIL = VREF − 0.5V.
