1.前言在最近一年期间,由以Intel 公司,Cogar公司和AMS 公司为首的几家公司出售了大容量半导体存储器,正式的大容量半导体存储器的时代临近了。那么,从已有的几种半导体存储器中选择一种,设计适宜的存储器系统时,怎样判断才好呢?根据以前所发表的几种存储器,讨论一下对半导体存储器特性的见解。为了从产品规格表中读懂半导体存储器的特性,首要的是理解半导体存储器的工作原理。考虑到读懂半导体存储器的规格和理解半导体存储器,下面介绍有代表性的半导体存储器的工作原理。
1. INTRODUCTION In the most recent year, several companies, led by Intel, Cogar and AMS, have sold large-capacity semiconductor memories and the era of formal high-capacity semiconductor memories is approaching. So, from the existing several types of semiconductor memory, select a suitable memory system design, how to judge it? Based on several previously published memory, to discuss the characteristics of semiconductor memory, the view. In order to read the characteristics of the semiconductor memory from the product specification sheet, the first and foremost is to understand the working principle of the semiconductor memory. Taking into account the read semiconductor memory specifications and understanding of semiconductor memory, the following describes the working principle of a representative semiconductor memory.
