Electrical Specifications  
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.

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. VDDQ must be equal to VDD.  
2. VIH (max.) = 2.3V (pulse width 5ns).  
3. VIL (min.) = 0.5V (pulse width 5ns).  
4. All voltage referred to VSS and VSSQ must be same potential.  
5. VID (DC) and VID (AC) are the magnitude of the difference between the input level on CK and the input  
level on /CK.  
6. The value of VIX is expected to be 0.5 × VDDQ and must track variations in the DC level of the same.
