Abstract: A semiconductor device includes a substrate divided into a memory cell region and a logic region. A split gate electrode structure is formed in a memory cell region of a substrate. A silicon oxide layer is formed on a sidewall of the split gate electrode structure and a surface of the substrate. A word line is formed on the silicon oxide layer that is positioned on the sidewall of the split gate electrode structure. The word line has an upper width and a lower width. The lower width is greater than the upper width. A logic gate pattern is formed on a logic region of the substrate. The logic gate pattern has a thickness thinner than the lower width of the word line.

Abstract: Disclosed is a toy system for downloading digital contents via the internet and processing the downloaded digital contents through real time cooperation between a computer and a toy. The computer comprises a recording medium which stores digital contents and a digital contents driving program. The toy comprises a microprocessor, a communication port, a digital sound decoder, a speaker, a motor driving unit, a motor, an LED/lighting device and an LED/lighting device control unit. The digital contents comprise image data, first and second sound data and motion control data. The digital contents driving program processes the following steps: reading the digital contents; displaying the image data of the digital contents on a screen of the computer; outputting the second sound data of the digital contents to a speaker of the computer; and transmitting the first sound data and the motion control data of the digital contents as a packet form to the toy connected with the computer.
