7.2 Operating Temperature Condition
Note :
1. Operating Temperature is the case surface temperature on the center/top side of the DRAM.
7.3 Input DC Logic Level
7.4 Input AC Logic Level
Note :
1. For information related to V
7.5 AC Input Test Conditions
Note :
1. Input waveform timing is referenced to the input signal crossing through the V
2. The input signal minimum slew rate is to be maintained over the range from V
3. AC timings are referenced with input waveforms switching from V
