    Summary form only given. Rather than using the reversability of a magnetic memory cell, it is becoming necessary to develop a mass storage device with a very fast access time and a high execution speed, to the detriment of long-period storage. The purpose is to store 2-10 MB over more than 30-day periods. This type of memory shows dynamic characteristics similar to those of semiconductor memories.... View full abstract»
