Operating Temperature Condition
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.

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