Memory-a new era of fast dynamic RAMs (for video applications)

摘要

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 in parallel. Examples are cache DRAMs, enhanced DRAMs, synchronous DRAMs, and Rambus DRAMs, all described in this report.
