{"article":{"id":"2221344","title":"中国、モバイルメモリチップで韓国、米国との差を縮める","description":"中国の大手半導体企業が、新世代の先進モバイルメモリチップの製造に初めて成功し、韓国や米国のライバルとの差を縮める大きな一歩となった。","contentObject":"
長鑫メモリーテクノロジーズ（CXMT）は、サムスン電子が2018年に発売したメモリチップの世代に類似した、中国初の高度デュアルデータレート（LPDDR5）DRAMメモリチップの生産に成功したと発表した。
\nこの躍進は、米国が半導体分野における北京の発展を阻止するためにハイテク輸出を締め付けている中で起こった。
\n中国はこれまで、ASMLや日本の一部のサプライヤーの主要な高性能リソグラフィーシステムへのアクセスを阻止されてきた。
\n合肥に本社を置くCXMTによると、同社の製品の一つである12ギガバイト（GB）バージョンは、小米科技（Xiaomi）や伝聯（Transsion）などの中国のスマートフォン企業で使用されている。
\n同社によれば、新しいメモリチップは、従来の低電力DDR4Xと比較してデータ転送速度と容量が50パーセント向上し、消費電力も30パーセント削減するという。
\n以前、中国本土のテクノロジー大手、華為技術は、国産の先進チップを搭載したスマートフォン「Mate 60 Pro」で世界を驚かせた。
\n第三者による分析レポートでは、このチップは中国の最大手チップ製造会社であるSMICによって製造される可能性があると結論付けている。
\n今週、中央演算処理チップの開発を専門とするLoongson社も、2020年のIntel CPUと同等の性能を持つ3A6000チップを発表した。
\n2016年に設立されたCXMTは、世界のDRAM市場でサムスン電子やSKハイニックス、マイクロンテクノロジーなどの韓国のメモリチップ大手に追いつくための中国最大の希望となっている。
\nサムスンは2018年に業界初の8GB LPDDR5チップを発表し、2021年には14nmベースの16GB LPDDR5Xチップにアップデートして、前世代より1.3倍高速となる最大8,500メガビット/秒のデータ処理速度を実現しました。
\nSKハイニックスは2021年3月にLPDDR5モバイルDRAMの量産を開始し、一方マイクロンは2020年初頭にLPDDR5チップを発表し、XiaomiのMi 10スマートフォンに搭載されるとしていた。
\n10月に更新された米国の新規制では、リソグラフィー、エッチング、堆積、注入、洗浄を含む一連の主要なチップ製造設備がすべて輸出制限リストに載っており、北京の半導体生産能力をロジックチップでは約14nm、DRAMでは18nmハーフピッチ以下、3D NANDメモリチップでは128層という最低レベルに制限することを目指している。
\n（サウスカロライナ州立大学モーニングスター校によると）

著者の投稿を見る中国の大手半導体企業が、新世代の先進的モバイルメモリチップの製造に初めて成功し、韓国や米国のライバル企業との差を縮める大きな一歩となった。
長鑫メモリーテクノロジーズ（CXMT）は、サムスン電子が2018年に発売したメモリチップの世代に類似した、中国初の高度デュアルデータレート（LPDDR5）DRAMメモリチップの生産に成功したと発表した。
この躍進は、米国が半導体分野における北京の発展を阻止するためにハイテク輸出を締め付けている中で起こった。
中国はこれまで、ASMLや日本の一部のサプライヤーの主要な高性能リソグラフィーシステムへのアクセスを阻止されてきた。
合肥に本社を置くCXMTによると、同社の製品の一つである12ギガバイト（GB）バージョンは、小米科技（Xiaomi）や伝聯（Transsion）などの中国のスマートフォン企業で使用されている。
同社によれば、新しいメモリチップは、従来の低電力DDR4Xと比較してデータ転送速度と容量が50パーセント向上し、消費電力も30パーセント削減するという。
以前、中国本土のテクノロジー大手、華為技術は、国産の先進チップを搭載したスマートフォン「Mate 60 Pro」で世界を驚かせた。
第三者による分析レポートでは、このチップは中国の最大手チップ製造会社であるSMICによって製造される可能性があると結論付けている。
今週、中央演算処理チップの開発を専門とするLoongson社も、2020年のIntel CPUと同等の性能を持つ3A6000チップを発表した。
2016年に設立されたCXMTは、世界のDRAM市場でサムスン電子やSKハイニックス、マイクロンテクノロジーなどの韓国のメモリチップ大手に追いつくための中国最大の希望となっている。
サムスンは2018年に業界初の8GB LPDDR5チップを発表し、2021年には14nmベースの16GB LPDDR5Xチップにアップデートして、前世代より1.3倍高速となる最大8,500メガビット/秒のデータ処理速度を実現しました。
SKハイニックスは2021年3月にLPDDR5モバイルDRAMの量産を開始し、一方マイクロンは2020年初頭にLPDDR5チップを発表し、XiaomiのMi 10スマートフォンに搭載されるとしていた。
Theo quy định mới Mỹ vừa cập nhật vào tháng 10, một loạt thiết bị đúc chip quan trọng bao gồm in thạch bản, khắc, lắng đọng, cấy ghép và làm sạch đều nằm trong danh sách hạn chế xuất khẩu, nhằm giới hạn năng lực sản xuất bán dẫn Bắc Kinh ở mức thấp nhất, khoảng 14nm đối với chip logic, 18nm half-pitch với DRAM hoặc nhỏ hơn và 128 lớp với chip nhớ 3D NAND.
