摘要： 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).

摘要： A next read threshold is determined by determining a first number of solid state storage cells having a stored voltage which falls into a first voltage range and determining a second number of solid state storage cells having a stored voltage which falls into a second voltage range. A gradient is determine by taking a difference between the first number of solid state storage cells and the second number of solid state storage cells. The next read threshold is determined based at least in part on the gradient.

摘要： 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.

摘要： A first decoder performs decoding on each data set in a first plurality of data sets using a first code; each data set in the first plurality is stored on a different chip. It is determined if the first decoding is successful; if not, a second decoder performs a second decoding on each data set in a second plurality of data sets using a second code; each data set in the second plurality includes at least some data, after the first decoding using the first code, from each data set in the first plurality. The first decoder performs a third decoding on each data set in the first plurality using the first code, where each data set in the first plurality includes at least some data, after the second decoding using the second code, from each data set in the second plurality.
