Data Sheet E0240E20 (Ver. 2.0)
• 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.
Absolute Maximum Ratings
Voltage on any pin relative to VSS
–0.5 to VDD + 0.5
(≤ 4.6 (max.))
Supply voltage relative to VSS
–0.5 to +4.6
Short circuit output current
0 to +70
–55 to +125
Notes: 1. SDRAM device specification
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.
DC Operating Conditions (TA = 0 to +70°C) (SDRAM device specification)
Input high voltage
VDD + 0.3
Input low voltage
Notes: 1. The supply voltage with all VDD pins must be on the same level.
2. The supply voltage with all VSS pins must be on the same level.
3. VIH (max.) = VDD + 2.0V for pulse width ≤ 3ns at VDD.
4. VIL (min.) = VSS
− 2.0V for pulse width ≤ 3ns at VSS.
