Abstract: A method includes storing data in a memory that includes multiple analog memory cells. After storing the data, an interference caused by a first group of the analog memory cells to a second group of the analog memory cells is estimated. The data stored in the first group is reconstructed based on the estimated interference caused by the first group to the second group.

Abstract: A method includes decoding a code word of an Error Correction Code (ECC), which is representable by a set of check equations, by performing a sequence of iterations, such that each iteration involves processing of multiple variable nodes. For one or more selected variable nodes, a count of the check equations that are defined over one or more variables held respectively by the one or more selected variable nodes is evaluated, and, when the count meets a predefined skipping criterion, the one or more selected variable nodes are omitted from a given iteration in the sequence.

Abstract: A method includes programming a group of analog memory cells by writing respective analog values into the memory cells in the group. After programming the group, the analog values are read from the memory cells in the group using a set of read thresholds so as to produce readout results. Respective optimal positions for the read thresholds in the set are identified based on the readout results. A noise level in the readout results is estimated based on the identified optimal positions of the read thresholds.

Abstract: A method includes, in an Error Correction Code (ECC) decoder that includes variable nodes and check nodes, receiving in a given variable node Check-to-Variable (C2V) messages from a subset of the check nodes. Magnitudes for respective Variable-to-Check (V2C) messages to be sent to the check nodes in the subset are computed based on the received C2V messages. A single sign is computed, for use in all the V2C messages to be sent from the given variable node to the check nodes in the subset. The V2C messages are sent from the given variable node to the check nodes in the subset, such that each V2C message includes a respective magnitude and the single sign.
Abstract translation: 一种方法包括在包括变量节点和校验节点的纠错码（ECC）解码器中，从给定的变量节点接收来自校验节点的子集的“一对一变量”（C2V）消息。 基于接收到的C2V消息计算要发送到子集中的校验节点的相应可变检查（V2C）消息的幅度。 计算单个符号，用于从给定变量节点发送到子集中的校验节点的所有V2C消息。 V2C消息从给定的变量节点发送到子集中的校验节点，使得每个V2C消息包括相应的大小和单个符号。

Abstract: A method for data storage includes accepting data for storage in a memory including multiple analog memory cells. For each memory cell, a respective set of nominal analog values is assigned for representing data values to be stored in the memory cell, by choosing the nominal analog values for a given memory cell in a respective range that depends on interference between the given memory cell and at least one other memory cell in the memory. The data is stored in each memory cell using the respective selected set of the nominal analog values.
