Intel Says 18A May Reach Strong Margins by 2027; Notebook Chips on the Node Mark Fastest Ramp in 5 Years

　　Intel is betting heavily on 18A to support the company’s turnaround plan. According to The Register, Chief Financial Officer David Zinsner said that early last year Intel faced the challenge of trying to improve both performance and yield at the same time. The company later shifted its focus to stabilizing performance first, and with that objective largely achieved, it is now concentrating on improving yield month by month.　　Zinsner said Intel’s goal is to achieve yield levels that support strong margins, adding that the company is currently ahead of schedule to reach that target by the end of 2027, as the report highlights. He added that after Lip-Bu Tan joined the company, Intel began sharing more manufacturing data with its vendors. The increased collaboration helped improve yields and made a dramatic difference.　　Looking beyond 18A, Zinsner also expressed confidence in Intel’s 14A. According to the report, he said the company has adopted a more aggressive approach than it did with 18A, adding that yield and performance metrics are currently ahead of where 18A was at the same stage of development.　　Intel 3 and 18A Supply Set to Rise Amid Strong CPU Demand　　In addition to providing an update on Intel’s manufacturing roadmap, Zinsner highlighted growing supply from Intel 3 and 18A, according to Seeking Alpha. As cited by the report, he said Intel expects a meaningful increase in supply from both Intel 3 and 18A over the coming quarters to meet rising demand. He added that 18A-based notebook processors are ramping quickly and represent the company’s fastest-ramping product launch in at least the past five years.　　The company is also seeing rising CPU demand. According to The Register, Zinsner said it remains difficult to predict the full extent of future growth, but he expects the market to be substantial. He said the key challenge at present is supply, adding that Intel sees sufficient demand in the market and should be able to grow data center revenue meaningfully if it executes successfully on planned supply ramps.

Samsung Starts Shipping Industry-First HBM4E Samples 3 Months After HBM4 Ramp; Performance Up 20%+

　　Just months after rolling out HBM4 shipments in early 2026, Samsung has begun providing samples of the industry’s first 12-layer HBM4E to major global partners, according to the company’s latest press release.　　Given that HBM4 shares the same 1c DRAM process and 4nm base die architecture as HBM4E, and is already in mass production, industry observers suggest the newly shipped HBM4E samples are also well positioned to transition into mass production. Samsung adds that it plans to proceed with HBM4E mass production in line with client-specific timelines.　　Meanwhile, Samsung is also expanding mass production and supply of HBM4, which became the world’s first HBM4 to enter mass production and shipment in February. In December last year, Samsung’s HBM4 received top-tier evaluation after demonstrating an industry-leading 11.7Gbps speed in System-in-Package (SiP) testing, the final certification stage, the company adds.　　According to News1, the latest development makes Samsung the first to supply HBM4E. Industry observers cited by the report also noted that starting from HBM4, customer-specific design flexibility and stable large-scale supply capabilities will become even more critical. Against this backdrop, Samsung’s integrated strengths across memory, foundry, and advanced packaging are expected to stand out even more clearly, the report adds.　　HBM4E Upgrade with 20% Performance Boost, 30% Higher Capacity　　In terms of performance, Samsung notes that HBM4E marks a notable upgrade over the previous generation, offering a stable 14Gbps pin speed that can scale up to 16Gbps for more demanding AI workloads. Compared with HBM4, the new memory delivers over 20% higher performance and reaches bandwidth of up to 3.6TB/s per stack, significantly improving compute efficiency for large language models (LLMs) and next-generation AI systems.　　Additionally, Samsung’s 12-layer HBM4E is currently offered in a 48GB capacity, which is more than 30% higher than the previous generation. The company plans to expand the lineup to include 32GB (8-layer) and 64GB (16-layer) variants to better align with diverse customer requirements as well.　　From an efficiency standpoint, Samsung highlights that advanced low-power design techniques and an optimized packaging architecture have improved energy efficiency by 16% while reducing thermal resistance by more than 14% compared with the previous generation.　　HBM4E Progress Among Rivals　　Meanwhile, progress from SK hynix and Micron in HBM4E has come under closer market scrutiny following Samsung’s advances. According to Yonhap News Agency, SK hynix had initially planned to begin HBM4E sample shipments in the second half of this year, but recent reports indicate smoother-than-expected development progress, bringing forward its timeline.　　On the other hand, Micron said its first HBM4E product will follow JEDEC standards, with mass production ramp-up targeted for 2027, according to STOCK Analysis.

Micron More Upbeat on Outlook, Reportedly Sets 2027 HBM4E Ramp with TSMC for Standard, Custom Logic Dies

　　Two months after its March earnings call, Micron is turning more upbeat on its outlook, while providing additional details on its custom HBM development progress. At the J.P. Morgan 54th Annual Global Technology, Media and Communications Conference, Micron’s Global Operations EVP Manish Bhatia, via STOCK Analysis transcript, said the company’s first HBM4E will be a JEDEC-standard product, with ramp-up scheduled for 2027.　　While Micron is still using 1-beta DRAM for HBM4, Bhatia said the company is expected to transition to 1-gamma DRAM in the HBM4E era. He also confirmed that the logic dies for both standard and custom HBM4E are expected to be manufactured by TSMC.　　When asked about the margin profile of customized products, Bhatia, according to STOCK Analysis, highlighted that value creation stems from multiple proprietary layers: design innovation, robust core DRAM development, and advanced packaging.　　He emphasized that customization represents the next evolution of this value expansion, and as the value increases, customers are expected to be willing to pay for the added customization.　　Improving Outlook vs. Previous Earnings Call　　According to Bhatia, Micron now expects tight conditions across HBM, DRAM, and NAND to persist well beyond 2026. Thus, he noted that the financial outlook has strengthened since the company’s last earnings call, and it is on track for another substantial record free cash flow in fiscal Q3.　　Notably, Bhatia pointed out that while pricing has largely played out as expected, demand remains very strong. He added that the AI ecosystem is shifting from human interactions to agentic and even machine-to-machine workflows, with these agentic workloads increasingly driving inference demand. As inference takes up a larger share of workloads, memory is increasingly seen as a strategic asset for customers, he said.　　Against this backdrop, Micron said in March that it had secured its first strategic customer agreement—a five-year deal with a large customer. Since then, the company has made meaningful progress on additional SCAs, with other customers also showing strong interest in establishing similar strategic relationships with Micron, including in NAND, Bhatia said.　　India Capacity Reported Booked up　　Amid tight demand, Bhatia also said Micron’s global expansion is accelerating. He noted that its Idaho 1 site is progressing well, with the company pulling forward its wafer output timeline from the second half of 2027 to mid-2027.　　Surging memory demand is also driving ramp-up at Micron’s new semiconductor assembly and test facility in Sanand, Gujarat, which began operations in late February. In a separate report by Business Standard, Micron’s entire memory production capacity in India has been fully booked amid strong demand.　　According to a previous Business Standard report, at full capacity, the facility could account for up to 10% of Micron’s global output, supplying both domestic and international markets.　　Sumit Sadana, executive vice-president and chief business officer at Micron, reportedly told Indian media outlet The Economic Times that the global semiconductor memory shortage triggered by the AI boom is proving far more severe than many companies currently anticipate, with the crunch potentially extending well beyond 2028 despite aggressive capacity expansion across the industry.

Furthermore, as vehicle functionality becomes more advanced, the need for precise monitoring and control across a wide range of applications continues to increase, placing a greater importance on high-accuracy current sensing.　　A current sense amp indirectly measures the current flowing through a circuit by amplifying the miniscule voltage drop across a shunt resistor. The amplified signal is then sent to an ADC or comparator for system control and monitoring. ROHM’s automotive-grade current sense amps meet market demands by leveraging proven analog expertise. This enables high-accuracy current sensing with compatibility for both negative and high voltage environments, contributing to improved safety and reliability in automotive applications, particularly electric vehicles.　　These new products achieve greater space efficiency by integrating most of current sensing circuitry, typically comprised of an operational amplifier and discrete components, int o a single package. As a result, current detection is possible by simply connecting a shunt resistor. The devices also feature a two-stage amplifier configuration, consisting of a chopper amplifier at the input and an auto-zero amplifier at the output. Internal resistor matching for gain setting ensures stable, accurate current sensing (±1%) while minimizing the effects of temperature variations.　　Furthermore, current detection accuracy is maintained even when an external RC filter circuit added for noise suppression, significantly reducing design complexity and development time.
