摘要： Decoding associated with a second error correction code and a first error correction code is performed. Ns first and second-corrected segments of data, first sets of parity information, and second sets of parity information are intersegment interleaved to obtain intersegment interleaved data, where the Ns segments of data, the Ns first sets of parity information, and the Ns second sets of parity information have had decoding associated with the first and the second error correction code performed on them (Ns is the number of segments interleaved together). Decoding associated with a third error correction code is performed on the intersegment interleaved data and interleaved parity information to obtain at least third-corrected interleaved data. The third-corrected interleaved data is de-interleaved.

摘要： An indication is received that a word line has been read. The word line is part of a plurality of word lines (in solid state storage) which is divided into a plurality of groups. It is determined which group is associated with the read. A count of consecutive, at least potentially uninformative reads is updated based at least in part on the group associated with the read and a group associated with a prior read. It is determining if the count is greater than a threshold and in the event it is determined the count is greater than the threshold, a read disturb check is triggered.

摘要： A soft output detector is programmed with a first set of parameters. Soft information is generated according to the first set of parameters, including likelihood information that spans a maximum likelihood range. Error correction decoding is performed on the soft information generated according to the first set of parameters. In the event decoding is unsuccessful, the soft output detector is programmed with a second set of parameters, soft information according is generated to the second set of parameters (including likelihood information that is scaled down from the maximum likelihood range), and error correction decoding is performed on the soft information generated according to the second set of parameters.
