DDR SDRAM Memory
The DDR SDRAM memory module installed at J10 uses SSTL-2 signaling
and termination. A reference voltage of 1.25 V is supplied to banks 3 and
4 for SSTL-2 receiver biasing. On-board resistors provide fly-by
termination at the DDR SDRAM memory connector pins. J10 is the
SODIMM connector for the DDR SDRAM memory.
