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.

VDDQ must be equal to VDD.
VIH (max.) = 2.3V (pulse width
≤
5ns).
VIL (min.) =
−0.5V
(pulse width
≤
5ns).
All voltage referred to VSS and VSSQ must be same potential.
VID (DC) and VID (AC) are the magnitude of the difference between the input level on CK and the input
level on /CK.
