Abstract: An encoding method includes: receiving, by an encoder, an information for encoding; generating, by the encoder, a first portion codeword according to a first encoding rule and the information for encoding, wherein the first encoding rule is an encoding rule configured to generate LDPC code; generating, by the encoder, a second portion codeword according to a second encoding rule different from the first encoding rule and a double check region of the first portion codeword; and concatenating, by the encoder, the first portion codeword and the second portion codeword to generate a codeword. A plurality of trapping sets corresponding to the first encoding rule include at least one error bit within the double check region.

Abstract: Systems, devices, methods, and circuits for managing data security in storage devices. In one aspect, a storage device includes at least one memory device and a controller coupled to the at least one memory device. The controller is configured to: encrypt first data with a first type of cryptographic algorithm and encrypt second data with a second type of cryptographic algorithm. The first data is associated with a first security level, and the second data is associated with a second security level that is higher than the first security level. The second type of cryptographic algorithm has a greater encryption strength than the first type of cryptographic algorithm.

Abstract: Systems, methods, and apparatus including computer-readable mediums for determining read voltages for memory systems with machine learning (ML) are provided. In one aspect, a memory system includes a memory and a memory controller configured to: obtain a first reading output of memory data using a first read voltage corresponding to a first set of parameters associated with the memory data; if the first reading output fails to pass an Error Correction Code (ECC) test, obtain a second reading output of the memory data using a second read voltage corresponding to a second set of parameters associated with the memory data and including the first set of parameters, the second read voltage being generated using at least one ML algorithm based on the second set of parameters; and if the second reading output passes the ECC test, output the second reading output as a target reading output of the memory data.
