{"article":{"id2221344"","titleChina reduce la brecha con Corea del Sur y EE. UU. en chips de memoria para móviles""descriptionUna importante empresa china de semiconductores ha producido con éxito, por primera vez, una nueva generación de chips de memoria avanzados para móviles, un paso importante para reducir la brecha con sus rivales surcoreanos y estadounidenses.""contentObject""
ChangXin Memory Technologies (CXMT) anunció que ha producido con éxito el primer chip de memoria DRAM de doble velocidad de datos avanzada (LPDDR5) de China, similar a la generación de chips de memoria lanzada por Samsung Electronics en 2018.
\norteEste avance se produce en un momento en que Estados Unidos restringe las exportaciones de alta tecnología para frenar el desarrollo de Pekín en el sector de los semiconductores.
\norteHasta el momento, China ha tenido bloqueado el acceso a sistemas de litografía de alta gama clave de ASML, así como a algunos proveedores de Japón.
\norteSegún CXMT, con sede en Hefei, uno de sus productos, la versión de 12 gigabytes (GB), está siendo utilizado por compañías chinas de teléfonos inteligentes como Xiaomi y Transsion.
\norteLa compañía afirma que el nuevo chip de memoria ofrece una mejora del 50 por ciento en la velocidad y capacidad de transferencia de datos en comparación con el anterior DDR4X de bajo consumo, al tiempo que reduce el consumo de energía en un 30 por ciento.
\norteAnteriormente, el gigante tecnológico chino Huawei Technologies sorprendió al mundo con su modelo de teléfono inteligente Mate 60 Pro, equipado con avanzados chips de fabricación nacional.
\norteLos informes de análisis de terceros concluyen que el chip podría ser fabricado por SMIC, la principal fundición de chips de China.
\norteEsta semana, Loongson, una empresa especializada en el desarrollo de chips para procesadores centrales, también anunció el chip 3A6000 con una potencia equivalente a la de las CPU de Intel de 2020.
\norteFundada en 2016, CXMT representa la mejor esperanza de China para alcanzar a los gigantes surcoreanos de chips de memoria como Samsung Electronics y SK Hynix, así como a Micron Technology en el mercado global de DRAM.
\norteSamsung presentó el primer chip LPDDR5 de 8 GB de la industria en 2018 y lo actualizó al chip LPDDR5X de 16 GB basado en 14 nm en 2021, ofreciendo velocidades de procesamiento de datos de hasta 8.500 megabits por segundo, 1,3 veces más rápido que la generación anterior.
\norteSK Hynix comenzó la producción en masa de DRAM móvil LPDDR5 en marzo de 2021, mientras que Micron anunció chips LPDDR5 a principios de 2020, que según dijo se utilizarían en el teléfono inteligente Mi 10 de Xiaomi.
\norteSegún las nuevas regulaciones estadounidenses actualizadas en octubre, una serie de equipos clave para la fabricación de chips, incluidos los de litografía, grabado, deposición, implantación y limpieza, figuran en la lista de restricciones a la exportación, con el objetivo de limitar la capacidad de producción de semiconductores de Pekín al nivel más bajo, alrededor de 14 nm para chips lógicos, 18 nm de medio paso para DRAM o menos y 128 capas para chips de memoria NAND 3D.

Xem các bài viết của tác giảMột công ty bán dẫn hàng đầu của Trung Quốc lần đầu tiên sản xuất thành công chip nhớ di động tiên tiến thế hệ mới, bước tiến quan trọng trong việc thu hẹp khoảng cách với các đối thủ Hàn Quốc và Mỹ.
ChangXin Memory Technologies (CXMT) cho biết đã sản xuất thành công chip nhớ DRAM tốc độ dữ liệu kép (LPDDR5) tiên tiến đầu tiên của Trung Quốc, tương tự như thế hệ chip nhớ mà Samsung Electronics ra mắt năm 2018.
Bước đột phá đạt được trong bối cảnh Mỹ siết chặt xuất khẩu công nghệ cao nhằm cản trợ sự phát triển của Bắc Kinh trong lĩnh vực bán dẫn.
Đến nay, Trung Quốc đã bị chặn tiếp cận các hệ thống in thạch bản cao cấp quan trọng từ công ty ASML, cũng như một số nhà cung cấp từ Nhật Bản.
Theo CXMT có trụ sở tại Hợp Phì, một trong những sản phẩm của họ, phiên bản 12 gigabyte (GB), đang được sử dụng bởi các công ty smartphone Trung Quốc như Xiaomi và Transsion.
Công ty cho biết chip bộ nhớ mới mang lại sự cải thiện 50% về tốc độ và dung lượng truyền dữ liệu so với DDR4X tiêu thụ điện năng thấp trước đó, đồng thời giảm 30% mức tiêu thụ điện năng.
Trước đó, gã khổng lồ công nghệ đại lục, Huawei Technologies khiến cả thể giới bất ngờ với model smartphone Mate 60 Pro được trang bị chip tiên tiến sản xuất trong nước.
Các báo cáo phân tích của bên thứ ba kết luận rằng con chip này có thể được sản xuất bởi nhà máy đúc chip hàng đầu của Trung Quốc là SMIC.
Trong tuần này, Loongson, công ty chuyên phát triển chip xử lý trung tâm, cũng công bố chip 3A6000 có sức mạnh tương đương CPU Intel của năm 2020.
Được thành lập vào năm 2016, CXMT đại diện cho hy vọng lớn nhất của Trung Quốc trong việc bắt kịp các gã khổng lồ chip nhớ Hàn Quốc như Samsung Electronics và SK Hynix, cũng như Micron Technology trên thị trường DRAM toàn cầu.
Samsung trình làng chip LPDDR5 8GB đầu tiên trong ngành vào năm 2018 và cập nhật lên chip LPDDR5X 16GB dựa trên tiến trình 14 nm vào năm 2021, mang lại tốc độ xử lý dữ liệu lên tới 8.500 megabit/giây, nhanh gấp hơn 1,3 lần thế hệ trước.
SK Hynix bắt đầu sản xuất hàng loạt DRAM di động LPDDR5 vào tháng 3 năm 2021, trong khi Micron công bố chip LPDDR5 vào đầu năm 2020, hãng cho biết sẽ sử dụng chip này trong điện thoại thông minh Mi 10 của Xiaomi.
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.
