Samsung Electronics Co. Ltd. today demonstrated what it claims is the world's first 1Gbit mobile DRAM, meant to support higher data processing requirements in digital camcorders, and accommodate 5-megapixel and higher resolutions in digital still cameras.

The newly developed SDRAM operates at 664Mbits/sec. and was optimized to function at 1.8volts in maximizing battery life due to Samsung?s partial array self refresh (PASR) and temperature compensated self refresh (TCSR) technologies, the company said.

Samsung also unveiled other mobile technologies including a system-in-package (SiP) with a 300MHz mobile CPU, a 1Gbit NAND flash memory, a 256Mbit mobile DRAM, a 260K color display driver IC (DDI) for active matrix organic light emitting diodes (OLED), a quad video graphics array (QVGA) resolution one-chip DDI, and a 2.5-inch QVGA thin-film-transistor, liquid crystal display (TFT-LCD) for MP3 players.

The technologies were shown at an event in Taipei.

The SiP contains a 300MHz mobile CPU, a 1Gbit NAND Flash memory and a 256Mbit mobile DRAM, meant to accommodate increasingly larger data processing and storage needs of portable game consoles, handsets, camcorders and PDAs.

By combining memory and system LSI technology, Samsung said it is coupling proven components within advanced package technology to improve mobile system integration, reduce power consumption and minimize size limitations. SiPs also reduce interference between devices, adding significantly to system reliability, Samsung said.

The 260K color DDI for AM OLEDs uses Samsung's 0.25-micron process technology to reduce the size of the device and contains a common interchange format along with a 1.8V power level.

Samsung also demonstrated a high-resolution quad video graphics array (QVGA, 240xRGBx320 pixel) with a built-in timing controller IC, a source driver, a gate driver, 1.3Mbit SRAM and a power supply circuit. This five-in-one-chip solution was designed using 0.18-micron process technology and utilizes micro-pad pitching technology, the company said.
