    Abstract: Memory systems may include a memory storage, and a controller suitable for measuring a write amplification (WA) value of a first, current window, comparing the WA value for the first window with a previous WA value for a previous window, and calculating and setting a value of a ratio threshold based on the comparison of the WA value for the current window threshold to the WA value of the previous window threshold.

    Abstract: A method for decoding low-density parity check (LDPC) codes, includes computing an initial syndrome of an initial output, obtaining an initial number of unsatisfied checks based on the computed initial syndrome, and when the initial number of unsatisfied checks is greater than zero, computing a reliability value with a parity check, performing a bit flip operation, computing a subsequent syndrome of a subsequent output, and ending decoding when a number of unsatisfied checks obtained based on the computed subsequent syndrome is equal to zero.

    Abstract translation: 用于解码低密度奇偶校验（LDPC）码的方法包括计算初始输出的初始综合征，基于所计算的初始综合征获得不满足的检查的初始数目，以及当初始不满足检查数大于零时 利用奇偶校验计算可靠性值，执行位翻转操作，计算随后输出的后续校正子，以及当基于所计算的后续校正子获得的多个不满足的检查值等于零时，结束解码。

    Abstract: An amount of time and an error rate function are received, where the error rate function defines a relationship between a number of iterations associated with iterative decoding and an error rate. A testing error rate is determined based at least in part on the amount of time. The number of iterations which corresponds to the testing error rate in the error rate function is selected to be a testing number of iterations; the testing error rate and the testing number of iterations are associated with testing storage media using iterative decoding.

    Abstract: A plurality of partially-decoded codewords that have been processed at least once by a first and a second error correction decoder is stored. A plurality of metrics associated with how close a corresponding partially-decoded codeword is to being successfully decoded is stored. From the plurality of partially-decoded codewords, a codeword having a metric indicating that that codeword is the closest to being successfully decoded by the first error correction decoder and the second error correction decoder is selected. The selected codeword is output to the first error correction decoder.

    Abstract: A first bit position of a cell in solid state storage is read where a sorting bit is obtained using the read of the first bit position. A second bit position of the cell is read for a first time, including by setting a first read threshold associated with the second bit position to a first value and setting a second read threshold associated with the second bit position to a second value. The second bit position of the cell is read for a second time, including by setting the first read threshold to a third value and setting the second read threshold to a fourth value. A new value for the first read threshold and for the second read threshold is generated using the sorting bit, the first read, and the second read.
