APPARATUSES FOR SECURING PROGRAM CODE STORED IN A NON-VOLATILE MEMORY

摘要

An embodiment of an apparatus for securing program code stored in a non-volatile memory is introduced. A non-volatile memory contains a first region and a second region. Two NVMMCS (non-volatile memory management controllers) are respectively coupled to the two regions. A programming command-and-address decoder is coupled to the NVMMCS. The programming command-and-address decoder instructs the first NVMMC to erase data from the first region when receiving a command to erase the first region via a programming interface, and instructs the second NVMMC to erase data from the second region when receiving a command to erase the second region via the programming interface.

1. 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 are designated by different operation codes.
