1) Table below lists parameters and specifications for different storage capacity RIMM Modules that use 288 Mbit
RDRAM devices.
2) Average clock delay is defined as the average delay from finger to finger of all RSL clock nets (CTM, CTMN,
.....CFM and CFMN).
3.) If the RIMM module meets the folowwing specifications, then it is compliant to the specification. If the RIMM
.....module does not meet these specifications, then the specification can be adjusted by the
