All voltages are referenced to VSS (GND).
After power up, wait more than 200 µs and then, execute power on sequence and CBR (Auto) refresh before
proper device operation is achieved.
Exposing the device to stress above those listed in Absolute Maximum Ratings could cause
permanent damage. The device is not meant to be operated under conditions outside the limits
described in the operational section of this specification. Exposure to Absolute Maximum Rating
conditions for extended periods may affect device reliability.
2. VIH is allowed to exceed VDD up to 3.6V for the period shorter than or equal to 5ns.
3. VIL is allowed to outreach below VSS down to –1.0V for the period shorter than or equal to 5ns.
4. VIN (DC) specifies the allowable DC execution of each differential input.
5. VID (DC) specifies the input differential voltage required for switching.
6. VIH (CK) min assumed over VREF + 0.18V, VIL (CK) max assumed under VREF – 0.18V if measurement.
