Until recently, electronically addressable devices such as ferrite core, plated wire, semiconductor memories, and electromechanically addressable devices such as magnetic tapes, disks, and drums were the few technologies from which a computer system designer could build a memory system. A number of different new technologies and devices have been developed that close the "access gap"<sup>14</sup>between the two dissimilar technologies mentioned above. These include charge-coupled devices (CCD's),<sup>2</sup>bubble memories,<sup>4</sup>electron beam addressed memories (EBAM),<sup>17</sup>and domain tip propagation (DOT).<sup>16</sup>Other technologies like CMOS<sup>1</sup>and integrated injection logic (I<sup>2</sup>L),<sup>9</sup>compete directly with the existing technologies. Table 1 (see p. 46) shows the possibility of a six-level hierarchy and some cost and performance projections for these technologies.
