摘要
由于日语文字处理器需要存储汉字字体和字典，对高密度掩模可编程ROM (MROM)的需求迅速增加。例如，桌面出版使用mrom存储80m位固定数据。作者描述了一种64 Mb的MROM，它采用了“良好的对选择”作为一种冗余技术。采用扁平单元结构和银行选择架构以及0.8 μ m CMOS工艺，他们开发出了高密度64mb的MROM。
A 64 Mb MROM with good pair selection architecture
The needs for high density mask programmable ROM (MROM) have increased rapidly due to the demand for storing the Kanji character fonts and dictionaries used in Japanese word processors. For example, desktop publishing uses MROMs for 80 M bits fixed data. The authors describe a 64 Mb MROM which employs a 'good pair selection' as a type of redundancy technique. Employing the technology a flat cell structure and a bank selection architecture and a 0.8 mu m CMOS process, they have developed high density 64 Mb MROM.<>
