Patent ID: 6936888

Claim:
A semiconductor apparatus comprising: a nonvolatile memory; and a central processing unit; wherein said nonvolatile memory has a plurality of memory cells; wherein each said memory cell is a multi-bit memory cell including: a memory gate formed over a first semiconductor region with a first insulating film and a second insulating film interposed therebetween, a plurality of data bits being stored in the memory cell by trapping electrons at one or more of a plurality of selectable portions of said second insulating film beneath said memory gate; a first switch gate formed over said first semiconductor region to a first side of said memory gate with a third insulating film; a second switch gate formed over the first semiconductor region to a second side of said memory gate with a fourth insulating film, wherein said second side is opposite said first side across said memory gate; and a second semiconductor region and a third semiconductor region respectively formed adjacent to opposite sides of said first semiconductor region; and wherein said first nonvolatile memory is capable of storing a program and data; and wherein said central processing unit executes said program read from said first nonvolatile memory.
