Patent number: 8259504Abstract: Multi-stage pulses are used to program/erase the memory so as to reduce the slow program/erase bit issue. A first predetermined voltage bias is applied to a memory cell for a predetermined number of times. Each time the voltage bias is applied to the memory cell the memory is verified against a criterion. If the verification failed after the predetermined number of times applying the first predetermined voltage bias, a second predetermined voltage bias is applied to program/erase the nonvolatile memory. If the verification failed after applying the second predetermined voltage bias, a third predetermined voltage bias is applied to program/erase the nonvolatile memory.Type: GrantFiled: July 15, 2009Date of Patent: September 4, 2012Assignee: eMemory Technology Inc.Inventors: Yun-Jen Ting, Kai-Yuan Hsiao
