Solid state: An update: CCD and bubble memories: Commercial units include 64-kbit charge-coupied-device and 92-kbit magnetic-bubble memories

Last year's emergence of both a single-chip 64-kbit (Ik = 1024) charge-coupled-device (CCD) and a 92-kbit magnetic-bubble memory (MBM) represents a leading edge of new memory-product developments. Already, laboratory design concepts and technologies are being aligned to create the next generation of these solid-state circuits. Concurrently, longer-range advanced laboratory programs are anticipating charge-coupled and magnetic-bubble memories in the multimegabit range by the early 1980s.
