摘要

本文介绍了一种应用于低成本多媒体系统的并行操作缓存DRAM (CDRAM)，它将程序和图形数据并存于主存中。DRAM和SRAM的并发操作完全消除了空闲周期。结果表明，采用0.6 /spl mu/m CMOS工艺的SRAM的平均存取时间为6.5 ns。闪存写入和直接读写在多媒体系统中也很有用。

A concurrent operating CDRAM for low cost multi-media

This paper describes a concurrent operating cache DRAM (CDRAM) for low cost multi-media systems, in which the program and graphic data coexist in the main memory. The concurrent operation of the DRAM and SRAM completely removes the idle cycles. As a result, the average access time is equal to the SRAM access time of 6.5 ns with 0.6 /spl mu/m CMOS process. The flash write and direct read/write are also useful for the multi-media systems.
