Samsung's OneDRAM super RAM promises to significantly boost the performance of portable gadgets by fusing two types of RAM on the one memory chip.

OneDRAM is targeted at cell phones and portable media players running multiple processors to cope with the demands of communications and multimedia. The new type of RAM combines two sticks of Dynamic Random Access Memory (DRAM) and one Static Random Access Memory (SRAM) one the chip. Until now portable devices with dual processors have incorporated both types of RAM separately, DRAM boosting performance for multimedia functions and SRAM speeding the up the transmission of data between the processors.

OneDRAM increases five-fold the speed of data processing between the CPUs for communications and for media. It also reduces power consumption by 30 percent and reduces the number of chips required - promising longer battery life and slimmer devices.

Samsung announced the development of 512MB, 133MHz OneDRAM stick at the 2006 International Electron Devices meeting in San Francisco. It expects OneDRAM to be introduced in handsets by the second half of 2007.
