1. Stresses greater than those listed may cause permanent damage to the device. This is a stress rating only and functional opera-
tion of the device at these or any other conditions above those indicated is not implied. Exposure to absolute maximum rating con-
dition for extended periods may affect reliability.
2. Maximum power occurs when all banks are active (refresh cycle).

1. All voltages referenced to VSS.
2. VIH may overshoot to VCC + 1.2V for pulse widths of ≤ 4.0ns with 3.3 Volt, or VCC + 2.0V for pulse widths of ≤ 4.0ns (or VCC + 1.0V
for ≤ 8.0ns) with 5.0 Volt. Additionally, VIL may undershoot to -2.0V for pulse widths ≤ 4.0ns (or -1.0V for ≤ 8.0ns). Pulse widths
measured at 50% points with amplitude measured peak to DC reference.
