Abstract
Disclosed is a semiconductor memory device comprising a memory core including a plurality of random-access memory cells, an error correction code (ECC) circuit configured to generate parity of data written to the memory core, and a message authentication code (MAC) control circuit configured to generate a security key based on a physical unclonable function (PUF) source signal in response to a message authentication code generation command or detection of a hacking or security attack, and configured to control the ECC circuit to generate a MAC on target data using the security key, wherein the ECC circuit operates in one of an ECC mode for generating an ECC parity and a MAC mode for generating the MAC under the control of the MAC control circuit.
