Samsung Electronics says it has developed a prototype fusion memory chip that can significantly increase the data processing speed between processors in mobile applications.
Dubbed OneDRAM, the 133MHz 512Mbit device, is expected to be used in handhelds with 3D graphics. It incorporates a dual-port approach to significantly decrease 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 the data can be adjusted accordingly. This meets the JEDEC, low power, double-data-rate (LPDDR) memory standard, said the firm.
Aimed at applications with dual processors, the memory device will channel communications between the processors without the need for separate DRAM and SRAM buffer memory.
There are power savings too, said Samsung. “The OneDRAM reduces power consumption by 30 per cent,” said the firm.
Samsung said the memory devices could be introduced in to handsets as early as the second half of 2007.
