Abstract: A memory subsystem has multiple memory devices coupled to a command/address line and an error alert line, the error alert line delay-compensated to provide deterministic alert signal timing. The command/address line and the error alert line are connected between the memory devices and a memory controller that manages the memory devices. The command/address line is driven by the memory controller, and the error alert line is driven by the memory devices.

Abstract: Techniques are described for decoding a message. In one example, the techniques include obtaining a first message comprising a plurality of information bits and a plurality of parity bits, decoding the first message using an iterative decoding algorithm to generate a first bit sequence, generating a miscorrection metric based at least on the first bit sequence and one or more reliability values corresponding to one or more bits in the first message, determining whether a miscorrection happened in the decoder by comparing the miscorrection metric with a first threshold, and upon determining that a miscorrection did not happen, outputting the first bit sequence as a decoded message.

Abstract: Electromagnetic compatibility (EMC) of a system-on-a-chip (SoC) is enhanced by encoding at least a subset of control signals before the control signals are transmitted over a bus (e.g., a bus internal to a SoC) from a controller to an embedded nonvolatile memory (NVM). The error-detection code used causes an EMC event to introduce errors into the transmitted codewords with relatively high probability. In response to an error being detected in the transmitted codeword, a set of safeguarding operations are performed to prevent the data stored in the NVM from being uncontrollably changed.

Abstract: A semiconductor memory device includes a memory cell array, an error correction circuit, an error log register and a control logic circuit. The memory cell array includes a plurality of memory bank arrays and each of the memory bank arrays includes a plurality of pages. The control logic circuit is configured to control the error correction circuit to perform an ECC decoding sequentially on some of the pages designated at least one access address for detecting at least one bit error, in response to a first command received from a memory controller. The control logic circuit performs an error logging operation to write page error information into the error log register and the page error information includes a number of error occurrence on each of the some pages determined from the detecting.
