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).
