Samsung Electronics announced the latest monolithic 256Mbit, 32-bit wide Double Data Rate (DDR) device that offers the bandwidth needed for photo-realistic 3D gaming in handsets.  

The device is part of Samsung's product family of Mobile Synchronous DRAMs that are available as Single Data Rate (SDR) or Double Data Rate (DDR) devices, all of which meet the strict power and form factor requirements demanded by battery-powered handsets. The Mobile DDR x 32 device supports data transfer rates of up to 266Mbps per pin, for an aggregate bandwidth of 1.064GB per second incorporating 0.10um process technology to effectively implement the mobile memory characteristics.

Mobile DRAMs reduce the power consumption of the most popularly used DRAM, enabling OEMs to extend battery life in handsets such as smart phones, MP3 players and PDAs. At the same time, the use of DRAM-based memory solutions allows designers to add new functions to handsets without sacrificing performance or form factor.

On-chip features including Integrated Temperature Compensation Self Refresh Sensors (TCSR), Partial Array Self Refresh (PASR) and Deep Power Down Mode (DPD) help designers enable systems that more accurately manage power budgets to extend battery life.

Mobile DRAM products include SDR and DDR Mobile DRAMs with densities ranging from 64Mb to 512Mb. The Mobile DDR x 32 device is currently shipping as an engineering sample.

Samples are available from mid-May, with mass production scheduled in the second half of 2004.
