Samsung Fusion Memory 2H 2007 Page: 1
Samsung Electronics announced that it has developed a prototype fusion memory, named OneDRAM, that it claims significantly increases the data processing speed between processors in mobile applications. The company said it expects to introduce the product in handsets by the second half of 2007.
OneDRAM is expected to be specified in the design of handsets, game consoles and in other digital applications, especially those that use 3-dimensional (3D) graphics, the company highlighted.
The 512Mbit 133MHz device incorporates a dual-port approach to sharply decrease data processing time between processors, Samsung said. 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 new OneDRAM will channel data between the processors through a single chip eliminating the need to also specify DRAM and SRAM chips for buffer memory. Data managed by the processors is housed in a shared bank where the space for storing data can be adjusted accordingly. This meets the JEDEC low power double-data-rate (LPDDR) memory standard.
Samsung also noted that OneDRAM reduces power consumption by 30%, lessens the number of chips needed and minimizes area coverage by 50%, resulting in a five-fold increase in the speed of handsets and gaming console operations, longer battery life and slimmer handset designs.
A single OneDRAM chip can replace, at least, two mobile memory chips in high-end smart phones and other multimedia-rich handsets. In addition, by adjusting the hardware in the chipset, OneDRAM can cost-effectively reduce system circuitry, while maximizing overall operational efficiency, the company said.
