Integrated circuit having an enhanced fuseless fuse structure, a method of manufacturing the same and a data structure for use with the fuseless fuse structure

摘要

An enhanced fuseless fuse structure is provided herein. Additionally, an IC with an enhanced fuseless fuse structure, a data structure that can be used with this structure and a method of manufacturing an IC are disclosed herein. In one embodiment, the IC includes: (1) a fuse wrapper configured to decode fuseless fuse data for controlling the fuses, (2) JTAG registers configured to store fuse register values in designated blocks, wherein the fuse register values and the designated blocks are determined from the fuseless fuse data and (3) options registers configurable by software to store fuse override data for modifying the fuse register values.
