Abstract
A system-on-a-chip (SOC) includes a memory system, a data processor and a read only memory (ROM). The memory system includes random access memory and a memory controller. The data processor includes at least one functional block that communicates data with the memory system via the memory controller. The ROM stores data and one or more parity bits for detecting and correcting errors in the data. The data includes chip information and/or security information for the SOC. A method of using the SOC includes storing data in the ROM that includes chip information and/or security information for the SOC; storing in the ROM the one or more parity bits for the data; reading the data and the one or more parity bits from the ROM; detecting and correcting errors in the data using the one or more parity bits; and outputting the corrected data.
