Samsung has developed memory technology that it says 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 is a prototype fusion memory chip that cuts out the inter-memory transfer. The 133MHz 512MB chip 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 improve circuit efficiency. 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, thus 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.
