7.2 Operating Temperature Condition
NOTE :
1. Operating Temperature is the case surface temperature on the center/top side of the DRAM. For the measurement conditions, please refer to JESD51.2 standard.
2. At 85 - 95 °C operation temperature range, doubling refresh commands in frequency to a 32ms period ( tREFI=3.9 us ) is required, and to enter to self refresh mode at this

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
