memory density
1.Three interesting subjects are presented in the following: ( 1) the vertical Bloch line may be utilised for making the memory of super high density, (2) macroscopic quantum tunnel of magnetisrr may develop into the smallest size quantum computer from the electronic computer, (3) it is the best technology that replace freon destroing ozone layer of atmosphere with the magnetic refrigeration near by rocrn temperature.
4.Single event multiple upset (SEMU) experimental results of high-density static random access memory (SRAM) are presented.
5.Wireless sensor networks(WSN) have restrictions due to energy,memory, and communication ability. This paper relates the QoS(quality of service) with the node density and its control strategies given for rectangular,circular,and various elliptical areas and designs for a dynamic adjusting mechanism based on the Gur Game algorithm.
10.The ultra-high-density Bloch line memory (BLM) uses negative vertical-Bloch-line (VBL) pairs in the walls of hard domains as information carriers. It is important to investigate the stability of the vertical-Bloch-lines for developing the BLM and enriching the theory of Magnetic domain walls.
