Disclosed is a method of operating a storage controller which is configured to communicate with a non-volatile memory device. The method includes receiving count data from the non-volatile memory device, determining a pre-read voltage based on the count data, sending a pre-read request using the pre-read voltage to the non-volatile memory device, receiving pre-read data from the non-volatile memory device responsive to sending the pre-read request, calculating a decoding value corresponding to the pre-read data, and generating read voltage information based on the count data and the decoding value, and the decoding value predicts an error voltage of the pre-read data.

Storage controller generating read voltages for soft decision decoding based on read information and decoding information, storage device including the same, and operating method thereof

A memory controller includes a processor, which is configured to determine one of a first operation mode and a second operation mode as an operation mode based on a lifespan or retention of a memory device. The processor is configured to transmit to the memory device, a read command for obtaining hard decision (HD) data and a first piece of SD data during a time period of a single read, or a read command for obtaining a second piece of SD data from a plurality of reads. A decoding circuit is configured to perform iterative decoding based on the first piece of SD data or the second piece of SD data. The first operation mode is for sequentially transmitting the coarse SD read command and the fine SD read command to the memory device, whereas the second operation mode is for transmitting the fine SD read command.

ECC decoder and memory controller including the same

Disclosed is a storage device which includes a nonvolatile memory device, and a memory controller that performs a read operation on the nonvolatile memory device and performs an error correction operation on data read in the read operation. In the error correction operation, the memory controller estimates an error rate of the read data, and determines whether to perform a read retry operation based on the estimated error rate.

Provided is a 5generation (5G) or 6generation (6G) communication system for supporting higher data rates after 4G communication systems such as long term evolution (LTE). A communication method of a user equipment (UE) includes receiving, from a base station (BS), information about a decoding mode including bit information corresponding to the number of times of perturbation, receiving data from the BS on a Physical Downlink Shared Channel (PDSCH), and decoding the received data based on the information about the decoding mode, wherein the information about the decoding mode may be generated based on service information including at least one of Quality of Service (QoS), a service priority, packet delay performance, packet error probability performance, a requirement, or a data transmission scheme.
