Data coding methods for a communication between semiconductor chips

Abstract

In a data encoding method for a communication between semiconductor chips, a data sequence is received. The data sequence includes multiple characters and multiple identification codes coupled to the characters, respectively. The data sequence is stored in a buffer in a unit of a predetermined number of pairs of characters and identification codes. Whether at least one control character is stored in the buffer is determined based on the identification codes stored in the buffer. When at least one control character is stored in the buffer, the at least one control character is converted to at least one internal control character, respectively. When multiple control characters are stored in the buffer, at least one internal control character includes a reference number representing a location of a sequentially next control character in the buffer. A first type data block is generated. The first type data block includes data characters stored in the buffer and the at least one internal control character.
