Abstract

An electronic device and a code patching method are provided. The electronic device includes a processor, a read-only memory (ROM), and a one-time programmable (OTP) memory. The ROM stores a boot code, and the boot code includes at least one checkpoint code segment. The OTP memory stores at least one patch code. The processor executes the boot code and queries whether there is a corresponding patch code in the OTP memory when the checkpoint code segment is executed, and if yes, executes the corresponding patch code.
