Note:
1. Input waveform timing is referenced to the input signal crossing through the VIH/IL(AC) level applied to the device under test.
2. The input signal minimum slew rate is to be maintained over the range from VREF to VIH(AC) min for rising edges and the range from VREF to VIL(AC)
max for falling edges as shown in the below figure.
3. AC timings are referenced with input waveforms switching from VIL(AC) to VIH(AC) on the positive transitions and VIH(AC) to VIL(AC) on the negative
transitions.

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 temperature range, an EMRS command is required to change internal refresh rate.
