Fusion for faster chips

Samsung Electronics has developed a prototype fusion memory chip that can significantly increase the data processing speed between processors in mobile applications.

Samsung expects to use its fusion solution OneDRAM in phone handsets, game consoles and in other digital applications, especially those that use 3D graphics.

The 133MHz 512Mb device incorporates a dual-port approach to reduce the time that it takes to transfer data between processors. Data managed by the processors is housed in a shared bank where the space for storing data can be adjusted accordingly. This meets the Joint Electron Device Engineering Council (JEDEC) low power double-data-rate (LPDDR) memory standard.

Due to rapidly increasing demand for multimedia features in mobile applications, designers have been specifying the use of two separate processors; a communication processor and a media processor. The OneDRAM will channel data between the processors through a single chip eliminating the need to specify DRAM and SRAM chips for buffer memory.
