微創科技的HBM4E預示著AI GPU及其他用途的客製化記憶體新時代

本週,微創科技(Micron)提供了其HBM4和HBM4E計劃的最新進展。下一代的HBM4記憶體擁有2048位的介面,預計將於2026年開始大規模生產,而HBM4E則會在隨後的幾年推出。除了提供比HBM4更高的數據傳輸速率外,HBM4E還將引入客製化基底晶片的選項,這將為行業帶來根本性的變革。

毫無疑問,HBM4以其2048位的記憶體介面令人印象深刻。然而,HBM4E將更具吸引力,因為它使微創能為特定客戶提供客製化的基底晶片,從而提供更優化的解決方案,並可能增加額外功能。這些客製化邏輯晶片將由台積電(TSMC)使用先進的製程技術製造,能夠容納更多的快取和邏輯電路,以提升性能和功能。

微創科技總裁兼首席執行官Sanjay Mehrotra表示:“HBM4E將通過為某些客戶提供客製化邏輯基底晶片的選項,利用TSMC的先進邏輯製造工藝,為記憶體行業帶來根本性的變革。我們預計這一客製化能力將推動微創的財務表現改善。”

目前,我們只能猜測微創如何計劃客製化其HBM4E基底邏輯晶片。可能的選項長得令人驚訝,包括增強的快取、針對特定應用(如AI、高效能計算及網絡等)的自定義介面協議、記憶體間傳輸能力、可變介面寬度、先進的電壓調整及功耗管理,以及客製化的ECC和/或安全算法。需注意的是,這些仍屬於推測,目前尚不清楚是否有實際的JEDEC標準支持這類客製化。

微創表示,HBM4E產品的開發工作正在與多家客戶進行中,因此我們可以期待不同客戶將採用不同配置的基底晶片。這標誌著定制記憶體解決方案朝向需求龐大的AI、高效能計算、網絡及其他應用邁進。HBM4E的客製化解決方案如何與Marvell本月初推出的客製化HBM(cHBM4)方案相比,尚待觀察。

微創的HBM4將使用該公司在其成熟的1β(第5代10納米級製程技術)上製造的DRAM,並放置於一個擁有2048位寬介面的基底晶片上,數據傳輸速率約為6.4 GT/s,這將為每堆疊提供理論峰值帶寬達1.64 TB/s。微創計劃在2026年大規模提升HBM4的生產,這與Nvidia的Vera Rubin及AMD的Instinct MI400系列GPU在AI及高效能計算應用的推出時期相吻合。有趣的是,三星和SK海力士據說將會使用第6代10納米級製造技術來生產其HBM4產品。

微創本週還透露,其為Nvidia的Blackwell處理器提供的8-Hi HBM3E設備的出貨已經全面開展。該公司的12-Hi HBM3E堆疊正在其主要客戶那裡進行測試,據報導,客戶對結果表示滿意。

微創的HBM3E 12-Hi堆疊被預期將用於AMD的Instinct MI325X和MI355X加速器,以及Nvidia的Blackwell B300系列計算GPU,適用於AI和高效能計算工作負載。

這一進展顯示出記憶體技術的快速演變,尤其是在AI和高效能計算需求日益增加的背景下。微創的客製化計劃不僅能滿足市場需求,還可能重新定義記憶體設計的標準。隨著行業競爭的加劇,未來的記憶體解決方案將更加多樣化和專業化,這將為各類應用開創更多可能性。

Base Setup
keep 100 percent facial information adherence of the attached image and turn her into a lone night hiker standing in the shallow river at the mouth of the canyon, captured as a live action photograph or movie still, not an illustration or CGI render, with an alluring, confident, quietly sexy mood.

Shot and Camera
Three quarter body shot from slightly low height on the riverbank, placing her on the left third while the water leads into the dark canyon and the star filled sky dominates the top of the frame, preserving the original wide vertical composition.

Identity and Pose
She has a slim athletic build, natural proportions, medium length loose hair, and lightly tanned skin, 8k Photorealistic and hyper realistic. She stands barefoot in the water with one leg forward, hips relaxed, wearing a fitted cropped technical top and separate high waisted trail shorts with an open lightweight jacket slipping off one shoulder, one hand loosely holding a headlamp at her side and the other brushing hair from her face as she looks up at the stars.

Lighting and Environment
Keep the soft starlight and faint glow from the distant horizon, giving a gentle rim on her shoulders and hair while a subtle fill from the reflected sky reveals her features. The canyon walls, river reflections, pebbled shore, and dense star field stay exactly like the reference, with small ripples around her feet grounding her in the water.

Masking and Constraints
Change only by adding the subject and her outfit, keep lighting, perspective, white balance, canyon geometry, and river reflections the same, with realistic scale, body proportions, and clear contact between feet and water surface. Change only the requested element and keep lighting, perspective, white balance, pose, face geometry, body proportions, and silhouette the same, and absolutely avoid added text, painterly or toon styling, CGI look, blown highlights, banding, plastic skin, overly tidy backgrounds, or floating feet while requiring consistent perspective, consistent white balance, subtle film like grain, and physically correct contact shadows and reflections. A futuristic humanoid male with eyes closed, illuminated by glowing turquoise bio-energy lines flowing across his face, hair, and upper body. Ultra-detailed anatomical light patterns resembling neural circuits and energy veins. Soft volumetric rim-lighting, dark sci-fi background, ethereal glow, hyper-realistic skin texture, holographic aura. High-definition digital art, surreal yet serene expression, sleek hair highlighted by luminous strands. Cinematic lighting, 8K resolution, ultra-sharp, moody and atmospheric composition.

Drone hovers slightly in front and above him, capturing both his face clearly and the giant statue towering behind.
