ডিজাইন নোট
Place decoupling capacitors (0.1uF and 1uF) close to each VDD and VDDQ pin. Use a solid ground plane and minimize trace lengths for DQ and DQS signals to reduce noise and signal integrity issues.
The FBGA-96 package has a thermal resistance of approximately 20°C/W. At 1.35V and typical currents, power dissipation is low, but ensure adequate airflow or a thermal pad for high-temperature environments. Monitor case temperature to stay within 95°C.
Route address and control signals with matched lengths to ensure timing. Use series termination resistors (22-33 ohm) for DQ and DQS lines. Follow the layout guidelines in the Samsung datasheet for optimal performance.
