Samsung Electronics Co. demonstrated the 1Gigabit (Gb) mobile DRAM, and unveiled five other leading edge mobile technologies
The Samsung's advancements announced included:- System-in-Package (SiP) with a 300MHz mobile CPU;
- 1Gigabit (Gb) NAND flash memory;
- 256Megabit (Mb) mobile DRAM;
- 260K color display driver IC (DDI) for active matrix OLEDs (organic light emitting diodes);
- qVGA resolution one-chip DDI;
- 2.5-inch qVGA TFT LCD for MP3 players;
Advanced System-in-Package
Conference attendees were shown Samsung's new SiP - the first package containing
a 300MHz mobile CPU, a 1Gb NAND Flash memory and a 256Mb mobile DRAM. By combining memory
and system LSI technology, Samsung 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.
High Density Mobile DRAM
The new 1Gb mobile DRAM will support higher data processing requirements in graphics-enhanced
digital camcorders, while accommodating five megapixel and higher resolutions in digital still
cameras.
The newly developed SDRAM operates at 664 megabytes per second and has been optimized to function at 1.8 volts in maximizing battery life through the use of Samsung proprietary partial array self refresh (PASR) and temperature compensated self refresh (TCSR) technologies.
Display Driver ICs
Samsung's 260K color display driver IC (DDI) for AM OLEDs utilizes 0.25um process
technology to reduce the size of the device to approximately 40 percent of leading
competitive models. The DDI for AM OLED features a quarter common interchange format
(qCIF, 176xRGBx240 pixel) along with a 1.8 volt power level.
With its new AM OLED application, Samsung now has developed the widest range of DDI
technology from STN-, TFT-LCD and AM OLED.
Also Samsung announced a high resolution quad video graphics array (qVGA, 240xRGBx320 pixel). The qVGA DDI device features a built-in timing controller IC, a source driver, a gate driver, 1.3Mb SRAM and a power supply circuit. This five-in-one-chip solution was designed using 0.18um process technology and utilizes micro-pad pitching technology.
TFT LCD For MP3s
In its final public unveiling at the Mobile Forum, Samsung previewed a TFT LCD for MP3 players.
The new 2.5-inch panel is 2.5-inches features crisp QVGA display resolution. Samsung proprietary
Vertical Alignment (VA) technology enables wide viewing angles for optimal viewing of music
videos and other visual displays that accompany MP3 music files.
