Abstract: A set of decisions is determined based at last in part on a set of samples. For a given sample in the set of samples, a low frequency noise estimate is estimated based at least in part on (1) at least some samples from the set of samples and (2) at least some decisions from the set of decisions. A reduced noise sample is generated by removing the low frequency noise estimate from the given sample.

Abstract: 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.

Abstract: An analog front end is adjusted by determining a signal quality based at least in part on digital sample(s). If the signal quality satisfies one or more criteria, a data independent gain gradient and a data independent offset gradient are selected to adjust the analog front end, where the two gradients are generated without taking into consideration an instantaneous value of an expected signal. If the signal quality does not satisfy the criteria, a decision directed gain gradient and a decision directed offset gradient are selected to adjust the analog front end, where the two gradients are generated based at least in part on decision(s).

Abstract: A value read back from storage and a set of bins are received. Each bin in the set of bins has a bin range. A bin corresponding to the read-back value is selected from the set of bins. The bin range of the selected bin is adjusted, based at least in part on the read-back value, so that the read-back value is more centered within the selected bin after adjustment.

Abstract: A starting read threshold is received. A first offset and a second offset is determined. A first read is performed at the starting read threshold offset by the first offset to obtain a first hard read value and a second read is performed at the starting read threshold offset by the second offset to obtain a second hard read value. A soft read value is generated based at least in part on the first hard read value and the second hard read value.

Abstract: A locality associated with a read request is identified based at least in part on a read address included in the read request. A predicted read address is generated based at least in part on the locality. It is decided whether to permit the predicted read address to be prefetched; in the event it is decided to permit the predicted read address to be prefetched, data from the predicted read address is prefetched and the prefetched data is stored in a prefetch cache.

Abstract: A read is performed using a first iteration of a read threshold voltage that is set to a default voltage to obtain a first characteristic. A second iteration of the read threshold voltage is generated using the default voltage and an offset. A read is performed using the second iteration of the read threshold voltage to obtain a second characteristic. A third iteration of the read threshold voltage is generated using the first and second characteristics. A read is performed using the third iteration of the read threshold voltage to obtain a third characteristic. It is determined if the third characteristic is one of the two characteristics closest to a stored characteristic. If so, a fourth iteration of the read threshold voltage is generated using the two closest characteristics.

Abstract: 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.
