Product business growth driven by transition from DDR4 to DDR5, increasing market share from 25% to 40%.
Total addressable market (TAM) for chipsets is about $2B, with new technologies like MRDIMM and client solutions expanding opportunities.
Growth in server and AI server markets, with more memory channels per processor and higher module content per server.
AI adoption accelerates DDR5 demand and increases both capacity and bandwidth requirements in servers.
Product and technology evolution
RCD chips are core to the business, with PMIC and companion chips ramping up as critical components in DDR5 modules.
PMIC revenue contribution is increasing, expected to reach high single digits of product revenue by Q4, with further growth into 2026.
MRDIMM technology multiplies module content value by 4x, with ramp expected in 2026–2027 as next-gen platforms launch.
Company aims for 40–50% market share in new product categories, leveraging first-to-market advantage and full chipset offerings.
Client market entry begins with high-speed platforms, with long-term TAM of $100–200M as speeds increase.
Competitive landscape and market dynamics
Main competitors for RCD chips are Renesas and Montage; for PMIC, Renesas and MPS.
AI servers require both HBM and traditional DRAM, with company providing HBM IP for integration into accelerators.
JEDEC standardization of new architectures like SOCAMM opens further opportunities for controller and power management chips.
Server channel count is increasing (8 to 12 to 16, with talks of 20), driving incremental chipset demand.

One of the very few apps you could call perfect. If something was to add to it, maybe the share price of the company when you search for it, but it's already excellent.
