Abstract: A method of operating a data storage device according to an exemplary embodiment of the present inventive concepts includes generating at least one pseudo noise (PN) sequence using logical information and physical information for the data storage device, and converting first data into second data using the at least one PN sequence. Generating the at least one PN sequence includes generating a random seed based on the logical information and the physical information, and generating the at least one PN sequence using the random seed. The logical information may be a logical page address for the data storage device, and the physical information may be a physical page address for the data storage device.

Abstract: An electronic device includes a memory storing data from an external source, an application processing unit (APU) transmitting a secret key and public key generation command, an isolated execution environment (IEE) generating a secret key in response to the secret key generation command, generating a public key based on the secret key in response to the public key generation command, and storing the secret key, and a non-volatile memory performing write and read operations depending on a request of the APU. When the data are stored in the memory, the APU transmits a public key request to the IEE and in response the IEE transfers the public key to the APU through a mailbox protocol. The APU generates a ciphertext by performing homomorphic encryption on the data based on an encryption key in the public key, and classifies and stores the public key and the ciphertext in the non-volatile memory.

Abstract: Provided is a device and method for encoding and decoding to implement maximum transition avoidance coding with minimum overhead. An exemplary device performs encoding and/or decoding, by using sub-block lookup tables representing correlations between some bit values in a data burst and symbols, a combining lookup table selectively interconnecting the sub-block lookup tables based on remaining bit values of the data burst, and a codeword decoding lookup table designating the sub-block lookup tables corresponding to the symbols of each of received codewords.

Abstract: A stacked neuromorphic device includes a logic die including a control circuit and configured to communicate with a host, and core dies stacked on the logic die and connected to the logic die via through silicon vias (TSVs) extending through the core dies. The core dies include a neuromorphic core die including a synapse array connected to row lines and column lines. The synapse array includes synapses configured to store weights and perform a calculation based on the weights and input data. The weights are included in layers of a neural network system. And the control circuit provides the weights to the neuromorphic core die through the TSVs and controls data transmission by the neuromorphic core die.
