The present disclosure provides a data encoding method, a decoding method, a related device, and a storage medium. The data encoding method first passes a first bit stream of an original encoded data through a logical operation to obtain a second bit stream. Then, through signal determination, negating processing, and insertion of corresponding flag bit, encoded data having a certain jump amplitude is obtained. A problem that signal is prone to error in transmission process is solved, reliability of coding is improved, and signal transmission is facilitated.

A Controller Area Network, CAN, bit stream sampling apparatus for a CAN controller, the apparatus configured to receive a bit stream from a CAN transceiver, the apparatus configured to: detect rising edges in said bit stream; detect, separately, falling edges in said bit stream; and generate a restored non-return-to-zero coded bit stream based at least on said detected falling edges and said detected rising edges.

The present disclosure describes aspects of pulse-based writing for magnetic storage media. In some aspects, a pulse-based writer of magnetic storage media determines that a string of data bits having a same polarity corresponds to a magnet longer than a threshold associated with a magnetic media writer. The pulse-based writer inserts, into the string of data bits, a transition to a polarity opposite to the same polarity of the string of data bits. The string of data bits including the inserted transition is then transmitted to the magnetic media writer to cause a write head of the writer to pulse while writing the magnet to magnetic storage media. Various aspects may also implement a control signal to mask a transition or control polarity of the magnetic media writer. By so doing, magnets may be written to the magnetic storage media more efficiently or with less distortion to neighboring tracks.

Methods, systems, and devices for error correction on a memory device are described. Examples may include a memory die having an array of memory cells including a plurality of banks. The memory die may further include a first error correcting code (ECC) circuit coupled with a first bank of memory cells, where the first ECC circuit is configured to perform operations associated with a first access operation (e.g., write operation) of the first bank of memory cells. The memory die may further include a second ECC circuit coupled with the first bank of memory cells, where the second ECC circuit is configured to perform ECC operations associated with a second access operation (e.g., read operation) of the first bank. In some cases, the first ECC circuit may be located under the footprint of the array and the second ECC circuit may be located outside the footprint of the array.

Techniques for encoding data are described herein. The method includes receiving a block payload at a physical layer to be transmitted via a data bus. The method includes establishing a block header comprising an arrangement of bits, the block header defining two block header types, wherein a hamming distance between block header types is at least four.

Examples are disclosed that relate to encoding data on a data-storage medium. The method comprises obtaining a representation of a measurement performed on the data-storage medium, the representation being based on a previously recorded pattern of data encoded in the data-storage medium in a layout that defines a plurality of data locations. The method further comprises inputting the representation into a data decoder comprising a trained machine-learning function, and obtaining from the data decoder, for each data location of the layout, a plurality of probability values, wherein each probability value is associated with a corresponding data value and represents the probability that the corresponding data value matches the actual data value in the previously recorded pattern of data at a same location in the layout.
