Notes :
1. DQ wiring may differ from that described
in this drawing; however DQ/DM/DQS
relationships are maintained as shown.
VDDID strap connections:

SDRAMs (D0 to D15), SPD

VDDID
Open
(for memory device VDD, VDDQ)
Strap out (open): VDD = VDDQ
* D0 to D15 : 512M bits DDR SDRAM
U0 : 2k bit EEPROM
Strap in (closed): VDD ≠ VDDQ
2. The SDA pull-up registor is reguired due to
the open-drain/open-collector output.
3. The SCL pull-up registor is recommended,
because of the normal SCL lime inactive
"high" state.
