隨著手持行動裝置的硬體迅速發展，以現有的高階 Cortex-A15 架構來看，最高頻率可達 2.5 GHz 與支援最多 1TB 的記憶體所帶來的匯流排頻寬需求相當驚人。雖然現有的記憶體頻寬仍足以滿足需求，但在頻寬與省電性上還是有繼續改進的必要，記憶體大廠 Samsung 今日在其 Samsung Mobile Solutions Forum 中宣布可供行動裝置使用的 30 奈米製程 2GB LPDDR3 記憶體已可進入量產階段。LPDDR3 記憶體每個針腳的 I/O 傳輸量可達 1,600Mbps，在以雙通道模式運作下，匯流排頻寬可達 12.8GB/s，總體來說多出前代架構 50% 的傳輸能力。此外，Samsung 也宣布將開始量產 128GB eMMC 快閃記憶體晶片，預計可以進一步縮小並推升 SSD 的體積與容量，雖然這兩個產品已進入量產階段，但用上最新記憶體晶片的 SSD 大概我們一般人也買不起，且目前已知的最新旗艦機款也仍然是採用 LPDDR2 記憶體，之後會配置在哪些機種上也還不能確定，不過隨著之前 Samsung Exynos 5 Dual 技術白皮書公佈的內容來看，想必是指日可待的。跳轉主站或點擊來源連結可瀏覽更詳細的官方新聞稿。
Samsung Announces Production of Industry's First 2GB LPDDR3 Mobile Memory, Using 30nm-class Technology
SEOUL, South Korea--(BUSINESS WIRE)--Samsung Electronics Co., Ltd., a global leader in advanced semiconductor technology solutions, has begun mass producing the industry's first two gigabyte (GB), low power double-data-rate 3 (LPDDR3) memory, using 30 nanometer (nm) class* technology, for next-generation mobile devices.
"We will embrace greater technical cooperation with industry leading mobile device makers, as we continue to provide timely next-generation memory solutions like 2GB LPDDR3 DRAM, in helping to accelerate growth of the mobile memory market"
Samsung started mass production of the industry's most advanced mobile DRAM (dynamic random access memory) chip, only 10 months after it began producing the industry's first 30nm-class based 2GB LPDDR2 memory in October, 2011. The new LPDDR3, which marks the first time a 2GB LPDDR3 density is available in one space-saving package, utilizes four LPDDR3 chips stacked together. LPDDR3 is needed for fast processors, high resolution displays and 3D graphics in tablets and smartphones.
"We will embrace greater technical cooperation with industry leading mobile device makers, as we continue to provide timely next-generation memory solutions like 2GB LPDDR3 DRAM, in helping to accelerate growth of the mobile memory market," said Wanhoon Hong, executive vice president, Memory Sales & Marketing, Samsung Electronics. "Furthermore, with this rapid introduction of 2GB LPDDR3, we are moving very assertively to expand our global leadership on the premium side of our extensive memory portfolio."
The new 2GB LPDDR3 DRAM can transfer data at up to 1600 megabits per second (Mbps) per pin, which is approximately 50 percent faster than a LPDDR2 DRAM. And on the package level, it provides a data transmission rate up to 12.8 gigabytes per second (GB/s), which will enable playing of full HD video content in real-time on smartphones and tablets. The high data transfer rates allows LPDDR3 to exceed support for full HD video payback on screens exceeding the current market available four-inch measurement and enable real-time viewing without downloading the content for the full HD visual experience.
By providing an early extensive global supply of LPDDR3 DRAM to smartphone and tablet manufacturers, Samsung expects to see a significant increase in the adoption of 2GB mobile DRAM.
