Abstract: A customer replaceable unit monitor (CRUM) integrated circuit (IC) includes: a secure module configured to receive an encryption key and an encrypted test code from outside; and a CRUM module controlled by the secure module. The secure module may perform authorization on the basis of the received encryption key. The secure module may perform decryption of the encrypted test code to generate a decrypted test code. The secure module may store the decrypted test code in a volatile memory. The secure module may generate a test command based on the decrypted test code in the volatile memory, and provide the test command to the CRUM module.

Abstract: A smart card is provided. The smart card includes a peripheral circuit configured to control a fingerprint sensing array and generate a raw image, an authentication information processing module configured to process the raw image into fingerprint information for verification, a security module configured to determine whether the fingerprint information for verification matches registered fingerprint information to determine usage approval or disapproval for a payment request, and an active shield overlapping the security module. The peripheral circuit, the authentication information processing module, and the security module are integrated into one chip.

Abstract: A memory device includes an address generator which generates a first physical address and a second physical address different from the first physical address. A first nonvolatile memory includes the first physical address, and a second nonvolatile memory includes the second physical address. An attack detecting circuit detects whether the first and second nonvolatile memories are attacked. The attack detecting circuit receives first data from the first nonvolatile memory and receives second data from the second nonvolatile memory, compares the first data and the second data with each other, and determines whether the first and second nonvolatile memories are attacked on the basis of a comparison result of the first data and the second data.
