对于用作扩展存储器的连续取数的MOS存储器,在要求大容量和高传输率的同时,又要求刷新处理不能影响数据传输率,这就给存储器的刷新设计带来了难题。 1.目前国内外对半导体存储器的刷新处理办法 第一种是集中刷新法。这种刷新法把所有刷新周期集中连续地进行。它要求在刷新
For the MOS memory used as a continuous access memory for extended memory, it is required that the refresh processing can not affect the data transfer rate while requiring large capacity and high transfer rate, which brings challenges to the refresh design of the memory. 1. Currently at home and abroad on the semiconductor memory refresh the first way is to focus on refreshing method. This refresh method focuses all the refresh cycles continuously. It requires refreshing
