Abstract

A semiconductor device including an embedded memory and an Application Specific Integrated Circuit logic which is configured before the semiconductor device is packaged is presented. The Application Specific Integrated Circuit logic implements a plurality of functions. A fusible link in the embedded memory connected to one of the plurality of functions enables the function in the Application Specific Integrated Circuit. The function can be permanently disabled in the Application Specific Integrated Circuit by blowing the fusible link in the embedded memory while testing the embedded memory or after testing the embedded memory.
