Notes:
1. Thermal Impedance data is based on a number of of samples from mulitple lots and should be viewed as a typical number.
2. Please refer to JEDEC standard JESD51-6.
3. The characteristics of the test fixture PCB influence reported thermal characteristics of the device. Be advised that a good thermal path to
the PCB can result in cooling or heating of the RAM depending on PCB temperature.
