摘要： An optimal read threshold estimation method includes determining a flip difference corresponding to an optimal step size Δopt, estimating a first slope m1 at a first read point and a second slope m2 at a second read point, and obtaining an optimal read threshold (XLPopt) as the intersection of a first line with the first slope m1 and a second line with the second slope m2.

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.

摘要： Apparatus for chip-to-chip communications may include a first driving unit and a second driving unit. The first driving unit may receive input data, generate a first output data based on the input data, and output the first output data. The second driving unit may receive the input data, generate a second output data with a pre-emphasis peak and output the second output data. The second output data may be generated by delaying and inverting the input data, and have a predetermined weight.

摘要： Information associated with a neighborhood is obtained based at least in part on a source location. It is determined, based at least in part on the information associated with the determined neighborhood, whether to perform a copy back operation using a specified set of one or more read thresholds. In the event it is determined to perform the copy back operation using the specified set of read thresholds, the copy back operation is performed on the source location using the specified set of read thresholds.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： A read back bit sequence and charge constraint information are obtained. A lower bound on a number of bit errors associated with the read back bit sequence is determined based at least in part on the read back bit sequence and the charge constraint information. The lower bound and an error correction capability threshold associated with an error correction decoder are compared. In the event the lower bound is greater than or equal to the error correction capability threshold, an error correction decoding failure is predicted and in response to the prediction a component is configured to save power.
