  • Semiconductor device and communication
    Patent number: 10880135
    Abstract: In the conventional semiconductor device, the power consumed in ternary serial data communication cannot be reduced. According to one embodiment, the semiconductor device has a the transmission processing circuit 10 that converts the binary representation of binary Transmitted data Dbin_TX to a ternary transmitted data Dter_TX represented as a ternary number and generates a transmitted signal corresponding to this ternary Transmitted data Dter_TX, wherein the transmission processing circuit 10 verifies the frequency of occurrence of the values included in the ternary transmitted data Dter_TX, assigns the signal change pattern with the highest state transition to the transmitted signal logical level corresponding to the lowest occurrence value, and generates a transmitted signal.
    Type: Grant
