Patent number: 10459715Abstract: A semiconductor system comprises a nonvolatile memory storing a patch code, the patch code comprising a unique identifier (ID). An internal read only memory (IROM) stores a boot code, the boot code comprising a patch code execution function for executing the patch code and a linked register (LR) address for specifying a storage location where the patch code is to be executed. A static random access memory (SRAM) stores a copy of the patch code at the storage location, the copy of the patch code including the unique ID. A processor executes the copy of the patch code from the storage location. The processor executes the copy of the patch code stored at the storage location in the SRAM according to the comparison result.Type: GrantFiled: July 25, 2017Date of Patent: October 29, 2019Assignee: Samsung Electronics Co., Ltd.Inventors: Sang Uk Park, Bong Chun Kang, Cheong Woo Lee, Hee Dong Shin
