Samsung chip will enable faster mobiles

New memory technology also extends battery life

Samsung has invented a new memory technology that it claims will make mobiles work five times faster.

Smartphones and other multimedia portable digital devices currently have separate processors for communications and media processing. Each has its own buffer memory using DRAM and SRAM chips. Data, such as a video clip sent to the phone, has to be dealt with by each processor and pass through these separate memories.

Samsung's OneDRAM, however, is a prototype fusion memory chip that cuts out the inter-memory transfer. It is a 133MHz, 512MB chip that is dual-ported and has a shared memory bank. The Korean manufacturer says the product can replace two memory chips and enable circuit efficiencies too. It enables faster processing - up to five times faster - and can lower power consumption by 30 percent, so extending battery life.

The new chip is expected to be incorporated in smartphone handsets in the second half of 2007. It should also be included in games consoles and any other portable digital devices using 3D graphics.
