三菱电机公司研制成功世界最小的1兆位DRAM(动态随机存取存储器)已投放市场。该存储器采用三菱电机公司独自的极小封装技术,体积仅为以前的1兆位DRAM的四分之一,堪称是面向办公室自动化设备和书本型个人计算机等市场的战略商品。这一称作“VSOP封装”的新产品由于采用了比以往产品高一级的0.9μm处理工艺,既达到超薄型的封 Mitsubishi Electric Corporation successfully developed the world’s smallest 1 megabit DRAM (Dynamic Random Access Memory) has been put on the market. The memory, based on Mitsubishi’s proprietary ultra-small form factor technology, is one-fourth the size of previous 1 Mbit DRAM and represents a strategic commodity for markets such as office automation equipment and book-type personal computers. This new product, called the “VSOP package,” achieves ultra-thin sealing thanks to a 0.9μm process that is one level higher than ever before
