  • ORGANIC MEMORY DEVICE AND METHOD OF FABRICATING THE SAME
    Publication number: 20070170420
    Abstract: An organic memory device includes a top electrode, a bottom electrode, and a bistable organic polymer layer between the top and bottom electrodes. Moreover, the organic memory device further includes a surface treatment layer between the organic polymer layer and the bottom electrode. Because the surface treatment layer can stabilize the interface between the organic polymer layer and the bottom electrode, the reliability of the device may be promoted.

  • Pre-recorded compact disc and copy-limit method thereof
    Patent number: 6785218
    Abstract: A copy-limit pre-recorded CD (Compact Disc) and a copy-limit method protect the data recorded on the pre-recorded CD from copied onto a recordable CD. The pre-recorded CD (Compact Disc) includes a data area of the pre-recorded CD and an indivisible file. The storage capacity of a data area of the recordable CD is Z. The indivisible file is stored in the data area of the pre-recorded CD and has a file size Y which approximately ranges between Z+10 MB and Z+100 MB. The copying action is prohibited to proceed when the indivisible file with a size is larger than the storage capacity of the data area of a recordable CD is determined.
