What was the revenue generated by Rambus from its own CXL chips in 2022, 2023, and 2024
roach to take an IP offering. We focus on high-speed memory interface, GDDR and GDDM. And then we focus on high-speed series or high-speed serial interfaces, PCIE and CXL.
And on the security side, we focus on wood of trust. So this is a very, very focused strategy. And we're having traction with all of them. I would say that the emergence of new connectivity requirements in the data center is driving growth for our CXL and PCIE offering in the silicon IP business.
So people are buying from us either size of controllers that go into chips that feature CXL or PCIe interfaces. And the acquisition of AnalogX and PLA last year, are contributing quite a lot to that growth in demand. So there's -- we see a lot of growth there. we see a lot of growth in GDDR, high-speed interfaces.
And on the security side, we continue to see growth in our traditional markets. But as I said earlier, there are emerging markets that are really interested in security, automotive, and government in particular. So it's really across the board, I would say that the vast majority of our growth in 2022 is driven by PCI and CXL designs.
Mehdi Hosseini -- Susquehanna International Group -- Analyst
If I may just follow up to that. I'm under impression that the [Inaudible] CXL is not the next year CXL 2.0. So when you talk about opportunities in '22 related to PCIe 4.0 or CXL, are these more R&D related? And then on 2.0 comes out, CXL 2.0, then those R&D projects will scale into production? Is that the right way of thinking about it?
Luc Seraphin -- Chief Executive Officer
Yes. The one way to think about it is this. As Rambus, we have our own CXL product initiative. We are in full speed development of our CXL chips, and they will hit the market in something next year and begin production in 2024, but we are also selling building blocks, silicon IP to people who build their own chips that feature CXL or PCIe.
And that's a silicon IP sales. So we do sell the IP today. It's an IP sale, a license that we sell today that creates revenue and revenue growth as an IP sales today for our customer products that we hit the market in '22, '23, and 2024. So this kind of phasing approach to CXL.
We can sell the silicon IP today to people who develop CXL and PCIe-capable chips, but we're also developing our own chips that will hit the market in the same timeframe.
