8.0 Absolute Maximum DC Ratings
Note :
1. Stresses greater than those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating only and
2. Storage Temperature is the case surface temperature on the center/top side of the DRAM. For the measurement conditions, please refer to JESD51-2
9.0 AC & DC Operating Conditions
9.1 Recommended DC Operating Conditions (SSTL - 1.8)
Note : There is no specific device V
