SVDD
SPD Voltage. Used for signals SCL, SDA,
SWE, SA0, SA1 and SA2.
Serial Presence Detect Write Protect (active
high). When low, the SPD can be written as
well as read.
CMOS I/O Voltage. Used for signals CMD,
SCK, SIN, SOUT.
Supply voltage for the RDRAM core and
interface logic.
Logic threshold reference voltage for both
"Thru" Channel and "Term" Channel RSL
signals.
