Apparatuses for securing program code stored in a non-volatile memory

An apparatus for securing program code stored in a non-volatile memory, comprising:

• a non-volatile memory comprising a first region and a second region;
• a first NVMMC (non-volatile memory management controller) coupled to the first region;
• a second NVMMC coupled to the second region;
• and
• a programming command-and-address decoder coupled to the first NVMMC and the second NVMMC, instructing the first NVMMC to erase data from the first region when receiving a first command to erase the first region via a programming interface, and instructing the second NVMMC to erase data from the second region when receiving a second command to erase the second region via the programming interface,
• wherein the first command and the second command have different command names and are designated by different operation codes,
• wherein the first region stores a customized library and the second region stores a main program, which calls the customized library, when being executed, and
• wherein the programming command-and-address decoder receives the first command to erase the customized library and the programming command-and-address decoder receives the second command to erase the main program.
