Method and apparatus for parallel data interfacing using combined coding and recording medium therefor

摘要

A semiconductor device may include a coding lookup table unit including a plurality of coding lookup tables each of which is selected by a respectively selection signal, and a selection unit configured to receive one of N-bit parallel data and extract respective encoded data corresponding to the selection signal and to which the N-bit parallel data is mapped from the coding lookup table unit, and encoded data and extract respective N-bit parallel data corresponding to the selection signal and to which the encoded data is mapped from the coding lookup table unit, wherein N is 2 or an integer greater than 2, and wherein the coding lookup tables respectively store a plurality of coded data patterns that respectively correspond to patterns of the N-bit parallel data and are random temporally and spatially.

1. A semiconductor device, comprising:
a scrambling code generator configured to generate a scrambling code using a seed; a scrambler configured to scramble a first parallel data group, which includes at least two sets of N-bit parallel data, using the scrambling code and generate a second parallel data group, which includes at least two sets of N-bit scrambled parallel data, where N is 2 or an integer greater than 2; a balance encoding block configured to receive the second parallel data group, perform direct current (DC) balance encoding of the N-bit scrambled parallel data sets in the second parallel data group, and generate M-bit balance codes, where M is an integer greater than N; and an output driver configured to sequentially output the balance codes and the seed through a plurality of data lines.
