100 / 196 page ![]() 100 Type 2 pSRAM pSRAM_Type02_15A0 May 3, 2004 Advance I n f o rmation Functional Description Legend:X = Don’t care (must be low or high state). Absolute Maximum Ratings Notes: 1. Stresses greater than those listed under "Absolute Maximum Ratings" section may cause permanent damage to the device. Functional operation should be restricted to be used under recommended operating condition. Exposure to absolute maximum rating conditions longer than 1 second may affect reliability. DC Recommended Operating Conditions Notes: 1. TA=-40 to 85°C, otherwise specified. 2. Overshoot: VCC+1.0V in case of pulse width ≤ 20ns. 3. Undershoot: -1.0V in case of pulse width ≤ 20ns. 4. Overshoot and undershoot are sampled, not 100% tested.
