众所周知,电脑上常用的Windows Media Player、Winamp等媒体播放器在播放音频文件的时候,一般会显示3D可视化效果。然而手机平台上,却长期缺乏支持3D可视化效果的音乐播放器(有的播放器仅仅显示2D可视化效果,如ULTRA MP3)。随着第一款支持3D可视化效果的音乐播放器cubix mp3 player的出现,我们终于可以在S60智能手机上享受到音色共舞的乐趣了;[编者按] 相似文献

A new stacked-nanowire device is proposed for 3-dimensional (3D) NAND flash memory application. Two single-crystalline Si nanowires are stacked in vertical direction using epitaxially grown SiGe/Si/SiGe/Si/SiGe layers on a Si substrate. Damascene gate process is adopted to make the gate-all-around (GAA) cell structure. Next to the gate, side-gate is made and device characteristics are controlled by the side-gate operations. By forming the virtual source/drain using the fringing field from the side-gate, short channel effect is effectively suppressed. Array design is also investigated for 3D NAND flash memory application. 相似文献

NAND flash chips have been innovated from two-dimension (2D) design which is based on planar NAND cells to three-dimension (3D) design which is based on vertical NAND cells. Two types of NAND flash technologies–charge-trap (CT) and floating-gate (FG) are presented in this paper to introduce NAND flash designs in detail. The physical characteristics of CT-based and FG-based 3D NAND flashes are analyzed. Moreover, the advantages and disadvantages of these two technologies in architecture, manufacture, interference and reliability are studied and compared. 相似文献

在封装的舞台上,三维集成技术因为在提高电子系统的性能和微型化方面效果卓著而引起重视。目前三维技术的手段一般采用较长的焊线来连接堆叠芯片和基层。新的三维概念仍处在开发阶段,但它将提供更短的互联,更高的互联密度,更低的成本。对于不同的应用,需要有相应且适宜的3D技术。 相似文献

数据保持力是NAND闪存重要的可靠性指标,本文基于用户在使用模式下,通过设计测试方法,研究了电荷捕获型3D NAND闪存初始阈值电压-2V至3V的范围内数据保持力特性.结果表明初始状态为编程态时,可以有效降低NAND闪存高温数据保留后的误码率,特别是随着擦写次数的增加,不同初始状态下电荷捕获型3D NAND闪存数据保持力差异更加明显,结论表明闪存最适宜存放的状态为0-1V,电荷捕获型3D NAND闪存器件应避免长期处于深擦除状态.并基于不同初始状态闪存高温数据保留后的数据保持力特性不同的现象进行了建模和演示,通过设计实验验证,机理解释模型符合实验结果.该研究可为电荷捕获型3D NAND闪存器件的长期存放状态提供理论参考. 相似文献

This paper discusses current status and recent advancements of 3D graphics on mobile platforms and describes open issues concerning its usage in different applications. We have treated two particular application fields. Firstly, we deal with problems of visualization of complex data structures on mobile devices. The implementation of a 3D visualization renderer on the Symbian platform for mobile devices is written as a C++ application and based on the DieselEngine® as a rendering engine. 3D visualization of data is generated in the form of a Virtual Reality Modelling Language (VRML) file meaning that actually any kind of 3D content written in VRML file format can be rendered on such a device. It was the result of a project the objective of which was to provide a user interface on a mobile platform displaying visualization of hierarchical Grid monitoring data. Secondly, we describe the system that brings face animation to embedded platforms. Face animation is considered to be one of the toughest tasks in computer animation today and its delivery to mobile platforms brings possibilities for development of new innovative and attractive services for the mobile market. 相似文献

A three-dimensional (3D) stacked bit-line NAND flash memory is investigated. The fabrication process flow for the formation of a laterally-recessed bit-line stack is described. Program operation is simulated using a stacked bit-line structure. Inter-layer interference (ILI) is addressed and the minimum isolation oxide thickness between stacked bit-lines is extracted. Simple device and array with the laterally-recessed bit-line stack are fabricated and electrical characteristics are measured. A new array architecture having a connection gate is designed for the 3D stacked bit-line NAND flash memory application. 相似文献
