New developments in memory technology are attempting to fill the void between main and secondary storage by providing alternatives to rotating storage devices with considerable performance advantages over the latter and at far less cost than main memory. The greater emphasis being placed on the use of virtual storage techniques in data processing systems has reaffirmed the need for fast, reliable, low cost memory devices with much reduced page swapping times. A principal developmental effort in this area is the development of moving magnetic domain techniques. The DOT, or Domain Tip, storage technology has an intrinsic capability for providing non-volatile, fast access, block or page-oriented memory systems. The relatively few steps required to manufacture DOT devices and the simple planar packages used offer the potential of low manufacturing cost. The memory medium, insensitive to temperature and to shock and vibration, is electronically passive with no connections being required between the storage medium and the drive or sense electronics. These factors suggest the capability of the DOT of providing highly reliable solid state memory. |
