商品描述

Emerging Memories: Technologies and Trends attempts to provide background and a description of the basic technology, function and properties of emerging as well as discussing potentially suitable applications.

With the many recent announcements of emerging memory technology development from large semiconductor companies, and with several start-up companies pursuing emerging memory products, there is considerable interest in the new technology.

Semiconductor memories have been around now for 30 years. They have increased fourfold in density about every three years from less than 1K-bit in 1972 to more than 1G-bit in 2002. Applications which historically permitted the technology to trade-off speed and power, now demand both high speed and low power. While the price has dropped from one dollar per 100 bits too less than one dollar per 100 megabits, the production technology has become so complex and expensive that the average multi billion-dollar company can no longer afford it. The circuits have reached geometries so small that semiconductor theories are being altered and fundamental limits are foreseen. While there are undoubtedly many years of life left in the old memory technology, the world is currently taking a hard look at whether there might be a better way.

This book explores a range of new memory products and technologies. The concept for some of these memories has been around for years. A few completely new. Some involve materials that have been in volume production in other type of devices for some time. Ferro-electrics, for example, have been used in capacitors for more than 30 years. In addition to looking at using known devices and materials in novel ways, there are new technologies being investigated such as DNA memories, light memories, molecular memories, and carbon nanotube memories, as well as the new polymer memories which hold the potential for the significant manufacturing reduction.

Emerging Memories: Technologies and Trends is a useful reference for the professional engineer in the semiconductor industry

商品描述(中文翻譯)

《新興記憶體:技術與趨勢》旨在提供新興記憶體的背景及其基本技術、功能和特性描述,並討論潛在的適用應用。近年來,許多大型半導體公司宣布了新興記憶體技術的發展,並且有幾家新創公司正在追求新興記憶體產品,因此對這項新技術的興趣相當高漲。

半導體記憶體已經存在了30年。自1972年以來,記憶體的密度每三年增加四倍,從不到1K位元增長到2002年的超過1G位元。歷史上,應用技術允許在速度和功耗之間進行權衡,但現在卻要求同時具備高速度和低功耗。儘管價格已從每100位元一美元降至每100兆位元不到一美元,但生產技術變得如此複雜和昂貴,以至於一般的數十億美元公司無法再承擔。電路的幾何尺寸已小到半導體理論正在被改變,並且預見到基本的限制。雖然舊有的記憶體技術無疑還有許多年的生命,但當前世界正在認真考慮是否存在更好的解決方案。

本書探討了一系列新的記憶體產品和技術。其中一些記憶體的概念已經存在多年,少數則是全新的。有些涉及已在其他類型設備中大量生產的材料。例如,鐵電材料已在電容器中使用超過30年。除了以新穎的方式使用已知的設備和材料外,還有新的技術正在被研究,例如DNA記憶體、光記憶體、分子記憶體和碳納米管記憶體,以及具有顯著製造成本降低潛力的新型聚合物記憶體。

《新興記憶體:技術與趨勢》是半導體行業專業工程師的有用參考資料。
