ABSOLUTE MAXIMUM RATINGS
NOTES:
Permanent device damage may occur if ABSOLUTE MAXIMUM RATINGS are exceeded.
Functional operation should be restricted to recommended operating condition.
Exposure to higher than recommended voltage for extended periods of time could affect device reliability.

NOTES :
1. Samsung can support VDDQ 2.5V(in general case) and 1.8V(in specific case) for VDD 2.5V products. Please contact to the
memory marketing team in Samsung Electronics when considering the use of VDDQ 1.8V(Min 1.65V).
2. VIH (max) = 3.0V AC.The overshoot voltage duration is
≤
3ns.
3. VIL (min) = -1.0V AC. The undershoot voltage duration is
≤
3ns.
4. Any input 0V
