Semiconductor device and communication

A semiconductor device comprising:

• a received signal definition table storage unit stores a plurality of received signal definition tables defining procedures for generating modulated ternary data from ternary data of a first predetermined length;
• a serial receiving unit for receives communication data including the modulated ternary data and a first received signal definition table used for generating the modulated ternary data from the plurality of received signal definition tables, and transmits the received communication data to circuits at a subsequent stage;
• a first encoder converts the modulated ternary data into the first predetermined length of ternary data based on the first received signal definition table;
• and
• a second encoder for converting the first predetermined length of ternary data into second predetermined length of binary data.
