Operating Temperature Condition
Input DC Logic Level
Input AC Logic Level
AC Input Test Conditions
Notes:
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
256MB, 512MB, 1GB Unbuffered SODIMMs
1. Operating Temperature is the case surface temperature on the center/top side of the DRAM. For the measurement conditions, please refer to
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
