Sun Microsystems Computer Corp and the Electronic Device Group of Mitsubishi Electronics America Inc have developed a memory technology called 3D RAM. This new frame buffer technology increases triangle rendering performance by a factor of approximately 10 compared to Video RAMs of similar cost, the firms claim. 3D RAM can render 100 pixel triangles at a rate of up to 1.8m triangles per second compared with 210,000 triangles per second with 2M Video RAMs. Devices based on 3D RAM will be available from Mitsubishi. Samples will be available by the end of this year, with full production to be started by the first quarter of 1995.
