Publication number: 20120087193Abstract: A threshold voltage distribution scheme for multi-level Flash cells where an erase threshold voltage and at least one programmed threshold voltage lie in an erase voltage domain. Having at least one programmed threshold voltage in the erase voltage domain reduces the Vread voltage level to minimize read disturb effects, while extending the life span of the multi-level Flash cells as the threshold voltage distance between programmed states is maximized. The erase voltage domain can be less than 0V while a program voltage domain is greater than 0V. Accordingly, circuits for program verifying and reading multi-level Flash cells having a programmed threshold voltage in the erase voltage domain and the program voltage domain use negative and positive high voltages.Type: ApplicationFiled: December 16, 2011Publication date: April 12, 2012Applicant: MOSAID TECHNOLOGIES INCORPORATEDInventor: Jin-Ji KIM

Patent number: 7200278Abstract: A digital image upscaling system enhances the visual quality of enlarged images by detecting diagonal edges and applying an appropriate scaling algorithm, such as a rotated bilinear scaling process, to output pixels associated with those edges. The rotated bilinear scaling process involves detecting diagonal edges and specifying a new frame of reference rotated 45° from the original frame of reference, and then selecting a rotated pixel set based on the new frame of reference. Bilinear interpolation in the new frame of reference using the rotated pixel set provides improved pixel data for the output pixel. Output pixels found not to be associated with diagonal edges are processed using standard bilinear interpolation.Type: GrantFiled: March 14, 2003Date of Patent: April 3, 2007Assignee: Huaya Microelectronics, LtdInventors: Wai Khaun Long, Jin Ji
