Are there Micron DDR chips with identical capacity but varying die designs?
Are there Micron DDR chips with identical capacity but varying die designs?
Hi
I understand your question. The choice between the two DDR chips depends on their specific die configurations—one with two dies and the other with four. The die plays a key role in determining compatibility, performance, and how they are integrated into your system.
It's not possible. DDR (also known as DDR1) has a maximum capacity of 1GB per DIMM. Therefore, how you can have 4GB DDR DIMMs is unclear. The difference would be in response time, latency, and heat dissipation. Various configurations exist, but technically spreading the heat makes RAM response time less noticeable. What really counts are timings and transfer rate. If both sets have identical rates and timings, it doesn't matter which you choose. However, if they differ, performance differences become apparent.
Hi
Actually, I wasn't referring to DDR.
I'm working with MT62F1G32D4DS -031 WT:B lpddr from Micron Technology in one of my projects.
This component has become outdated. For a replacement, I'm searching for an alternative and discovered the MT62F1G32D2DS-26 WT:C version.
The main change is in the die count. But I'm not sure why chips with identical memory capacities have different die structures. That's why I reached out.
Thanks for your reply.
I also have another question. The part that is no longer needed has a cycle time of 313ps, while the alternative I found has 218ps. Should I make any firmware adjustments here, or will the system automatically detect the change and handle the data accordingly?
Are you confident about the part number? After checking online, the information I found confirms it's DDR5 32GB single DIMM, not a dual 4GB unit as described.
Provided a more detailed assessment, confirming it is indeed 32Gb with SMD RAM rather than standard DIMM, which accounts for the 4GB total and LPDDR5 specification. (For conventional DIMMs, such a configuration isn't available.) Compatibility hinges on whether the logic board supports these modified RAM specifications after SMT placement and PCB soldering.
In fact, I'm not employing it in DIMM. Instead, I'm integrating it into my tailored embedded system that interacts with the CV72 SOC memory controller.
