Electrical Specifications

• All voltages are referenced to VSS (GND).

• After power up, wait more than 100 µs and then, execute Power on sequence and CBR (auto) Refresh before

proper device operation is achieved.

Caution

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.

Notes: 1. All voltage referred to VSS.

2. The supply voltage with all VDD and VDDQ pins must be on the same level.

3. The supply voltage with all VSS and VSSQ pins must be on the same level.

4. VIH (max.) = VDD + 2.0 V for pulse width ≤ 3ns at VDD.

5. VIL (min.) = VSS – 2.0 V for pulse width ≤ 3ns at VSS.
