A memory controller according to an embodiment includes a memory interface that reads out a received word from a non-volatile memory and a decoder that performs bounded distance decoding for the read received word. The decoder sets r.sub.m (r.sub.m is a natural number equal to or larger than 1) symbols of a plurality of symbols constituting the received word, as options of symbol positions at each of which an error is assumed, generates a test pattern in which m (m is a natural number equal to or larger than 1 and equal to or smaller than the r.sub.m) symbols of the r.sub.m symbols are objects of rewriting, generates test hard-decision values by rewriting each of hard-decision values of the m symbols that are objects of rewriting in the test pattern, among the symbols, and performs bounded distance decoding for the test hard-decision values.

A data compression method and a data decompression method are provided. The method includes pruning an original data including a plurality of weight parameters, identifying at least one first weight parameter of which at least one first value is not changed by the pruning, among multiple weight parameters included in the pruned original data, and obtaining a first index data including location information of the at least one first weight parameter of which the at least one first value is not changed, identifying at least one second weight parameter of which at least one second value is changed by the pruning, among the multiple weight parameters included in the pruned original data, and substituting the at least one second weight parameter of which the at least one second value is changed with a don't care parameter.

The disclosure is directed to a system, device and method for data storage on implantable magnetizable fabric. The system includes implantable magnetizable fabric coupled to a graft segment of a prosthesis for being delivered into a body of a subject. The system includes information written on the implantable magnetizable fabric. The system further includes a magnetic detection device capable of, after the prosthesis is delivered into the body of the subject, detecting the implantable magnetizable fabric and accessing at least a portion of the information.

An analog-to-digital converter (ADC) includes a digital-to-analog converter (DAC) that has a configurable capacitor array. Based on measurements of differential nonlinearity (DNL) and/or integral nonlinearity (INL) error by an external test computer system, an order for use of the DAC's capacitors can be determined so as to reduce DNL error aggregation, also called INL. The DAC includes a switch matrix that can be programmed by programming data supplied by the test computer system.

Methods, devices and systems enhance compression and decompression of data blocks of data values by selecting the best suited compression method and device among two or a plurality of compression methods and devices, which are combined together and which said compression methods and devices compress effectively data values of particular data types; said best suited compression method and device is selected using as main selection criterion the dominating data type in a data block by predicting the data types within said data block.

A method for efficient name coding in a storage system is provided. The method includes identifying common prefixes, common suffixes, and midsections of a plurality of strings in the storage system, and writing the common prefixes, midsections and common suffixes to a string table in the storage system. The method includes encoding each string of the plurality of strings as to position in the string table of prefix, midsection and suffix of the string, and writing the encoding of each string to memory in the storage system for the plurality of strings, in the storage system.

A data transmitter includes an encoder configured to encode first data to be transmitted, in accordance with an encoding rule and a transmitter configured to transmit the encoded first data. The encoder makes a change to the encoding rule, encodes the first data in accordance with the change in the encoding rule, and incorporates second data having content corresponding to the change in the encoding rule, into the first data.
