Rambus Inc. (NASDAQ: RMBS), a memory-chip company with deep exposure to artificial intelligence and data center markets, is gaining increasing attention from investors and analysts.
Shares of the company have surged nearly 30% over the past week, fueled by optimism about the critical role of memory technology in powering AI applications.
Rosenblatt Securities analyst Kevin Cassidy, who has long highlighted Rambus’s positioning in dynamic random-access memory (DRAM), raised his price target for the stock to $130 from $90 in a Wednesday note.
The new target represents a 34% premium to Tuesday’s closing price.
Memory chips gain spotlight in AI boom
The artificial intelligence boom has primarily drawn attention to chipmakers like Nvidia and Advanced Micro Devices, but memory-chip specialists are now emerging as crucial players in the ecosystem.
DRAM is particularly essential for enabling high-speed data transfers between processors and memory, making it indispensable for AI workloads and advanced gaming applications.
Rambus designs high-performance semiconductors and interface chips that help manage data movement between memory components and processors such as GPUs.
The company’s portfolio also includes GDDR (graphics double data rate) memory technology, which allows for rapid data transfer needed for high-intensity tasks.
Beyond data centers, Rambus’s products are used in automotive applications and security solutions.
Cassidy and his team at Rosenblatt described Rambus as a “pure-play leader in data center DRAM,” underscoring its strategic importance in AI infrastructure.
Recent data center deployment announcements suggest that demand for Rambus’s products could extend through at least 2026 and 2027.
Revenue growth outlook remains strong
According to Rosenblatt’s forecast, Rambus’s semiconductor revenue is expected to rise 40% year over year in 2025, followed by an additional 20% growth in 2026.
The analysts cited “increasing dollar content per server” and rising server shipments as the key drivers.
This optimistic outlook reflects broader momentum in the data center market, where companies are investing heavily to support AI applications.
Rambus’s technologies, which focus on optimizing memory bandwidth and efficiency, are viewed as critical enablers of these large-scale deployments.
Cassidy noted that the firm’s long-term investment thesis has centered on the growing importance of DRAM in AI deployment.
“That thesis is playing out above our expectations,” he wrote, adding that Rambus remains well-positioned to capitalize on these structural tailwinds.
Valuation overhang eases after accounting resolution
One factor that had weighed on Rambus’s valuation in the past was uncertainty surrounding revenue recognition tied to licensing agreements.
Recently, however, the company resolved key accounting issues, aligning its agreements with industry rules and clearing up investor concerns.
Cassidy suggested that this resolution provided clarity that helped unlock Rambus’s recent stock rally.
Even with the nearly 30% gain in the past week, the analyst maintained that the company’s growth story leaves “plenty of room to run” for investors.
As AI adoption accelerates and data center demand expands, Rambus’s role in delivering the memory technologies underpinning this shift is drawing overdue recognition.
For investors, the recent surge reflects both a re-rating of the stock and growing confidence that Rambus will continue to ride the AI wave well into the next decade.
