    The search for new dynamic RAM (DRAM) technologies to reduce memory access time and so unleash computer performance is discussed. The typical memory hierarchy of internal registers, cache, main memory, and mass storage is described. DRAM technologies that aim at simplifying this hierarchy by speeding up main memory to the point where the need for a separate, external cache is moot are examined.<... View full abstract»

    It is argued that HDTV will require even greater memory throughput than computers do, for future television features such as high-definition display and picture enhancement. Current TV memories are described, and the features of HDTV that require faster memories are examined. The constraints composed by DRAM characteristics on TV designers are considered.<<ETX>> View full abstract»

    Innovative circuit designs intended to bring inexpensive dynamic memories up to speed are discussed. The features of video DRAMs, the high-data-rate application that spurred the development of application-specific DRAMs that utilize wide on-chip buses, are described. Several new chips use the wide data buses within DRAMs to advantage; on most of them 1024 to 4096 memory locations may be accessed i... View full abstract»

    A proprietary scheme for a unified memory system that covers all design aspects to ensure fast display and quick computation is presented. This device replaces extant memory types and their interconnects with unique DRAMs, a high-performance, chip-to-chip interface, and a high speed channel. It delivers a byte of data every 2 ns for a block of information up to 256 bytes long. The features and per... View full abstract»

    Work on an open standard that defines a ring for linking fast memories and processors is discussed. The interface, called RamLink, will provide high performance even when dynamic RAMs (DRAMs) with internal caching mechanisms are ineffective. In addition to RAM, RamLink will support flash nonvolatile memory, read-only memory, and even memory-mapped disks. Mismatching, collision avoidance, and probl... View full abstract»

    Synchronous coupling of the power grids on either side of the former iron curtain is discussed. Presently, in power exchanges between eastern and western Europe, AC at 50 Hz is converted to DC and back again at the same frequency. Such a link is asynchronous. The advantages of switching to synchronized operation, whereby all generators producing the same frequency operate at exactly the same speed... View full abstract»
