Flash Technology: Challenges and Opportunities

概要

論文の詳細を見る
Flash memory is a rapidly growing segment of the semiconductor memory market. It occupies a unique place among semiconductor memories by offering the combination of non-volatility, electrical re-writability and high density. Several alternate Flash cell structures have evolved that offer differing tradeoffs for cost and performance. The Flash memory market has been valued over $1.9 Billion (US) in 1995 and accounts for about 3.5% of the overall semiconductor memory market. Flash memory is the fastest growing segment of the non-volatile semiconductor memory market. This paper examines the challenges and opportunities in Flash technology using ETOX^<TM> cells as an example. Flash poses some unique challenges in controlling tunneling and in voltage scaling. Flash also presents a unique opportunity for scaling storage density through multi-level cells.
