Samsung (Seoul, South Korea) said it expects the fusion memory, OneDRAM, to used in handsets, game consoles and in other digital applications, especially those that use three-dimensional graphics.

According to Samsung, the 133-MHz, 512-Mb OneDRAM device, successor to the company's OneNAND fusion memory, incorporates a dual-port approach designed to 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, Samsung said, meeting the JEDEC, low power, double-data-rate memory standard.

Designers have been specifying the use of separate communications and media processors to meet rapidly increasing demand for multimedia features in cellular handsets. OneDRAM will channel data between the processors through a single chip, eliminating the need to also specify DRAM and SRAM chips for buffer memory, according to Samsung.

Samsung claims the OneDRAM reduces power consumption by 30 percent, lessens the number of chips needed and minimizes area coverage by 50 percent, resulting in a five-fold increase in the speed of cell phone and gaming console operations, longer battery life and slimmer handset designs. A single OneDRAM can replace at least two mobile memories in high-end smart phones and other multimedia-rich handsets, according to the company.

Samsung said it expects OneDRAM to be introduced in handsets by the second half of 2007.
