Abstract :
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.
