Notes: 1. For DQ and DM: VREF = VREFDQ (DC).

2. See Overshoot and Undershoot Specifications section.

3. The AC peak noise on VREF may not allow VREF to deviate from VREFDQ (DC) by more than

1% VDD

(for reference: approx.

15 mV).

4. For reference: approx. VDD/2

15 mV.

5. VIH (DC) is used as a simplified symbol for VIHDQ (DC100)

6. VIL (DC) is used as a simplified symbol for VILDQ (DC100)

7. VIH(AC) is used as a simplified symbol for VIHDQ (AC150); VIHDQ (AC150) value is used when VREF

+ 0.150V is referenced.

8. VIL (AC) is used as a simplified symbol for VILDQ (AC150) ; VILDQ (AC150) value is used when VREF

 0.150V is referenced.
