RAMBUS MODULE
SPD Specification
For 144M RDRAM
(2nd Gen.)
based RIMM
REV. 1.03
February 2000
Revision History
Revision 1.0 (June
′99)
It is based on the RAMBUS SPD Specification 1.0 version.
Revision 1.01 (Oct.
′99)
Byte 53 : Add the plate temperature value, Tplate to 92°C.
Byte 54 ~ 60 : Add the current values for 356, 300MHz or 266MHz operation.
Byte 63 : Correct the checksum for bytes 0 ~ 62.
Byte 115 : Clear hexa value becase it is not used tCDLY=4 when CDLY0 = 2 & CDLY1= 0.
Byte 127 : Correct the checksum for bytes 99 ~ 126.
Revision 1.03 (Feb.
′00)
The Only difference from 1.02ver is to keep the previous OLD Part Number System.
Byte 9 : Add values(bit 7 = 0; S3 compatible) to ensure S3 resume compatibility.
Byte 53 : Add the values(bit 6 = 0; Non-Compliant thermal sensor) for proper thermal sensor trip operation.
