Samsung has invented new memory technology that it says will make mobiles work five times faster.
Smart phones and other multi-media 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. This enables it to channel data between the communications and media processors without a transfer operation. The new chip meets the JEDEC low power, double data rate (LPDDR) standard.
Samsung says a OneDRAM chip can replace two memory chips and enable circuit efficiencies as well. It enables faster processing, up to five times faster, minimises control board area coverage by up to half, and can lower power consumption by 30 percent, so extending battery life.
The new chip is expected to be incorporated in smart phone handsets in the second half of 2007. It should also be included in games consoles and any other portable digital devices using 3D graphics.
