What is the expected revenue for the fourth quarter of 2020 for the company FORM in terms of foundry and logic business
And then I've got a follow-up question for Shai.
Mike Slessor -- President and Chief Executive Officer
Quinn, it's Michael. I'll handle that one. The foundry and logic strength is quite broad-based as it was in the third quarter as well. If you take a look at our 10% customer list, you can see some nice strength across multiple leaders in the foundry and logic space there. We're seeing the same thing continue here in the fourth quarter, so it is reasonably diversified, nicely broad-based. A lot of the drivers we talked about before, certainly, 5G -- major 5G handset launches are behind that. Infrastructure data spending -- data center spending, some really nice robust trends continuing here through the back part of the year. On the China situation, we tried to give you a little more detail in the prepared remarks.
The domestic China business for us has been sort of a mid-single-digit percent of revenue for the past several quarters. Majority of our China business is serving the multinationals in the region. And as a consequence, you can imagine the major domestic foundry is not a really big business for us. Having said that, for sure, as a U.S. company, there have been some headwinds associated with serving them and other domestic China customers. And I think, like everybody else, we're working our way through investigating the different ways we can mitigate that, whether they be through licenses or other compliance activities.

Great. And then the other question for Shai, just you talked about a less favorable mix in the quarter. I guess I just look at foundry and logic strength with lower NAND and about flat DRAM, I would think that, that mix would generally be positive for you. So can you sort of walk us through within foundry and logic and perhaps the memory business. What in-segment mix shift maybe going on that would sort of offset what I would have thought to be a tailwind with the mix shifting toward foundry and logic?
Shai Shahar -- Chief Financial Officer
Sure, Quinn. That's a good observation. We did say in the past that if you look at the different markets we serve, historically or maybe on average, Systems has the highest gross margin followed by foundry and logic, then DRAM and then Flash. But a few things. First of all, there is some overlap there. There are cases that you can have the DRAM card with a higher gross margin than a foundry and logic card. And also the mix within these markets -- the product mix within these markets even within the same customer can change. So it's true that if you look at the trend for Q4, foundry and logic is expected to be higher, and Flash is expected to be down. But the mix within these markets also has an impact and that's why at the midpoint of the outlook range, we expect to have gross margin lower than Q3 even though revenue is a little higher.
Quinn Bolton -- Needham -- Analyst
Got it. And then, Shai, I may have missed it, but did you give a quarter-to-quarter sort of guidance for what the Systems business would do in the fourth quarter?
Shai Shahar -- Chief Financial Officer
We did not when we spoke about the 3, maybe the market.
Quinn Bolton -- Needham -- Analyst
Okay. Great. Thank you all. I'll be back in the queue.

[Operator Instructions] Our next question will come from the line of Carlin Lynch from B. Riley. Your line is now open.
Carlin Lynch -- B. Riley -- Analyst
Hey guys, this is Carlin on for Craig. Two quick questions. One, starting with you, Mike, you had talked, I think, previously about the Livermore plant asset purchase. If you could just give us an update on how that ramp is coming and what we can expect in terms of timing and production facility conversion, that would be great. And then I have a follow-up.
Mike Slessor -- President and Chief Executive Officer
Yes. I think we're still in the fairly early stages of that. To remind everyone, we bought close to 100,000 square foot building, which is going to be utilized entirely for manufacturing capacity adjacent to our existing footprint in Livermore, Califor
