RDIMM FAQs (2)

Can Vtt and Vref be supplied by the same supply in my system design?
With proper decoupling this can be an acceptable design. However, Micron recommends ensuring all supplies are separated. Vref tends to have more noise on it because it supplies signals that are regularly switching. A robust design would typically not connect these supplies due to the possibility of introducing this noise onto the Vtt plane which should be as stable as possible. Additionally, Vref requires much less current than Vtt.
Is there a set of trace lengths and routing rules that are standard for use when designing a system that uses a specific module technology and form factor?
No. A robust memory subsystem design that includes the use of 1 or more memory modules must be simulated in order to determine the optimum trace lengths, terminations. However, our design guides such as TN-47-01 and TN-41-08 have some best practices and design examples based on some typical system assumptions. This information is not meant to be the only way your system can be designed. It is a starting point and moreover an example of the steps used to determine the best design for your system.

DRAM Modules FAQs (5)

What is a "bank"?
A bank is an array of memory bits. Multiple arrays or banks are contained within a DRAM component. Depending on density, DRAM components may consist of 4 or 8 banks. For example, a bank may consist of 32 million rows, 4 bits across. This would equate to 128 megabits. Four of these banks in a single DRAM component would yield a 512Mb component.
What is the impedance tolerance of the driver in match-impedance mode relative to the expected value base on the perfect reference resistor connected to ZQ pin?
The impedance tolerance of the driver is ±15 percent.
Does thermal information change for IT parts?
Thermal information includes temperature limits and thermal impedance values. Temperature limits do change for IT parts (TC, TJ, and TA), but thermal impedance values (θJA, θJB, and θJC) do not because thermal impedance depends primarily on the package.
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.
Your particular board design should not be a cause of major concern. The pins can handle the VDD voltage regardless of the VDDQ voltage.
Should the ECC memory chip share chip select and CKE signals with the other two main memory chips in our point-to-point application?
The ECC chip(s) should share the same CKE and CS# as the other devices because they are accessed as the same piece of data.
