General Product Information

Is VREF required during self refresh? I would like to put DDR memory in self refresh mode and turn off power to the CPU (the system is battery-operated). Can I disable VREF and still have correct self refresh operation?
Does thermal information change for IT parts?
Should the ECC memory chip share chip select and CKE signals with the other two main memory chips in our point-to-point application?
My design was based on a specification stating the JTAG was relative to VDD (1.8V), but now we’ve discovered that JTAG is actually relative to VDDQ (1.5V). It’s a fairly significant board spin to change this; what do I risk by leaving the design as-is? I assume that the specification is still for VDDQ + 0.3V = 1.8V, but with CMOS parts there’s no way I can guarantee that it won’t swing past that on transitions.
