Chiny zmniejszają różnicę w stosunku do Korei Południowej i USA w dziedzinie układów pamięci mobilnej

{"article":{"id":"2221344","title":"Chiny zmniejszają dystans do Korei Południowej i USA w dziedzinie układów pamięci do urządzeń mobilnych","description":"Wiodąca chińska firma produkująca półprzewodniki po raz pierwszy z powodzeniem wyprodukowała nową generację zaawansowanych układów pamięci do urządzeń mobilnych, co stanowi ważny krok w kierunku zmniejszenia dystansu do konkurentów z Korei Południowej i USA.","contentObject":"

Firma ChangXin Memory Technologies (CXMT) poinformowała o pomyślnym wyprodukowaniu pierwszego w Chinach zaawansowanego układu pamięci DRAM o podwójnej szybkości transmisji danych (LPDDR5), podobnego do generacji układów pamięci wprowadzonych na rynek przez firmę Samsung Electronics w 2018 r.

Przełom nastąpił w momencie, gdy Stany Zjednoczone zaostrzyły politykę eksportową w sektorze zaawansowanych technologii, aby ograniczyć rozwój Pekinu w sektorze półprzewodników.

Do tej pory Chinom uniemożliwiono dostęp do najważniejszych, zaawansowanych systemów litograficznych firmy ASML, jak również do niektórych dostawców z Japonii.

Mówi się, że pamięć DRAM CXMT jest tak wydajna, jak produkt Samsunga wprowadzony na rynek w 2018 roku.

Według firmy CXMT z Hefei jeden z ich produktów, wersja o pojemności 12 gigabajtów (GB), jest używany przez chińskie firmy produkujące smartfony, takie jak Xiaomi i Transsion.

Firma twierdzi, że nowy układ pamięci oferuje o 50 procent większą prędkość przesyłu danych i większą pojemność w porównaniu z poprzednią, energooszczędną pamięcią DDR4X, a jednocześnie zmniejsza zużycie energii o 30 procent.

Wcześniej chiński gigant technologiczny Huawei Technologies zaskoczył świat modelem smartfona Mate 60 Pro, wyposażonym w zaawansowane układy scalone produkowane w Chinach.

Raporty niezależnych analiz wskazują, że układ scalony może wyprodukować największa chińska odlewnia układów scalonych, SMIC.

W tym tygodniu firma Loongson, specjalizująca się w produkcji układów centralnych, zapowiedziała również układ 3A6000 o mocy odpowiadającej procesorom Intel z 2020 roku.

Założona w 2016 r. firma CXMT jest największą nadzieją Chin na dogonienie południowokoreańskich gigantów w dziedzinie układów pamięci, takich jak Samsung Electronics i SK Hynix, a także Micron Technology na światowym rynku pamięci DRAM.

Samsung wprowadził na rynek pierwszy w branży 8-gigabajtowy układ LPDDR5 w 2018 r., a w 2021 r. zmodernizował go do 16-gigabajtowego układu LPDDR5X opartego na procesie technologicznym 14 nm. Zapewnia on prędkość przetwarzania danych sięgającą 8500 megabitów na sekundę, czyli 1,3 raza szybciej niż poprzednia generacja.

Firma SK Hynix rozpoczęła masową produkcję pamięci DRAM LPDDR5 do urządzeń mobilnych w marcu 2021 r., natomiast Micron ogłosił wprowadzenie na rynek układów LPDDR5 na początku 2020 r., które według firmy będą wykorzystywane w smartfonie Xiaomi Mi 10.

Zgodnie z nowymi przepisami USA, zaktualizowanymi w październiku, szereg kluczowych urządzeń do odlewania układów scalonych, w tym urządzenia do litografii, trawienia, osadzania, implantacji i czyszczenia, znalazło się na liście ograniczeń eksportowych. Celem jest ograniczenie zdolności produkcyjnych Pekinu w zakresie półprzewodników do najniższego poziomu, około 14 nm dla układów logicznych, 18 nm półrozstawu dla pamięci DRAM lub mniejszej i 128 warstw dla układów pamięci 3D NAND.

(Według SCMP)

Chińska firma niespodziewanie produkuje najnowocześniejsze na świecie układy pamięci

Według firmy analitycznej TechInsights, Yangtze Memory Technologies (YMTC) – wiodący chiński producent układów pamięci – z powodzeniem stworzył „najbardziej zaawansowany na świecie” układ pamięci 3D NAND.

Koreański producent układów pamięci bada pochodzenie podzespołów telefonu Mate 60 Pro

Producent SK Hynix (Korea) był zaskoczony informacją, że jego układ pamięci został wykorzystany w najnowszym modelu smartfona Mate 60 Pro koncernu Huawei (Chiny).

Południowokoreański gigant produkujący układy pamięci odnotował rekordową stratę

Południowokoreański gigant na rynku układów pamięci SK Hynix właśnie ogłosił swoje najnowsze kwartalne wyniki biznesowe, wykazując stratę w wysokości 3,4 biliona wonów (równowartość 2,54 miliarda dolarów).

Một 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.

DRAM của CXMT được đánh giá có sức mạnh tương đương sản phẩm Samsung ra mắt hồi năm 2018.

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.

Công ty Trung Quốc bất ngờ sản xuất chip nhớ hiện đại nhất thế giới

Theo hãng phân tích TechInsights, Yangtze Memory Technologies (YMTC) – công ty memory chip hàng đầu Trung Quốc – đã sản xuất thành công chip nhớ 3D NAND 'tiên tiến nhất thế giới'.

Hãng chip nhớ Hàn Quốc điều tra nguồn gốc linh kiện điện thoại Mate 60 Pro

Nhà sản xuất SK Hynix (Hàn Quốc) bất ngờ với thông tin chip nhớ của hãng được sử dụng trong mẫu smartphone Mate 60 Pro mới nhất của Tập đoàn Huawei (Trung Quốc).
