Abstract: A riding apparatus for children is disclosed. The riding apparatus of the present invention includes a main body (110), which has a handle (111) and a footrest (115), and support plates (120), which are installed in the main body and are placed upright at positions spaced apart from each other by a predetermined distance. The riding apparatus further includes an operating unit (300), which has a front rotary member (330), a rear rotary member (340), a front spring (350), a rear spring (351) and a connection bar (310). The front rotary member and the rear rotary member respectively have interlocking shafts (213) and (223). The riding apparatus further includes front legs (210) and rear legs (220), which are respectively fastened to the interlocking shafts (213) and (223). A one-way wheel assembly is provided on the lower end of each of the front and rear legs.

Abstract: The present invention relates generally to a phase change memory device and, more particularly, to a phase change memory cell array suitable for the implementation of a high-density memory device. The phase change memory cell array includes a first access transistor pair and a second access transistor pair formed on a semiconductor substrate to be adjacent to each other while each of the first and second access transistor pairs having a common drain, phase change resistance elements formed on source regions of the access transistors, respectively, and a semiconductor region formed on the same plane as the common drains to electrically connect the common drains of the first and second transistor pairs. The phase change memory cell array and the memory device of the present invention are suitable for the implementation of a high-density semiconductor device, and capable of improving the reliability of a contact forming process by securing a sufficient space for the contact forming process.
