SYSTEM ON CHIP, METHOD OF OPERATING THE SAME, AND DEVICES INCLUDING THE SYSTEM ON CHIP

摘要

A method of operating a system on chip (SoC) includes converting plain data into cipher data by using an encryption key and transmitting the cipher data directly to a memory controller which controls an operation of a non-volatile memory. The encryption key may be output by a one-time programmable (OTP) memory.

主权项

1. A system on chip (SoC) comprising:
a central processing unit (CPU); a volatile memory controller configured to receive plain data from an external volatile memory; an encryption engine configured to encrypt the plain data transmitted from the volatile memory controller into cipher data using an encryption key, the encryption key being input to the encryption engine in a secure mode by the CPU; a non-volatile memory controller configured to receive the cipher data from the encryption engine and to output the cipher data to an external non-volatile memory; and a storage medium configured to store the encryption key, wherein the encryption engine is directly connected to the non-volatile memory controller.
