Abstract
An artificial intelligence calculation semiconductor device is provided. The artificial intelligence calculation semiconductor device comprising: a control unit; and a MAC (Multiply and Accumulator) calculator which executes a homomorphic encryption calculation through the control unit, wherein the MAC calculator includes an NTT (Numeric Theoretic Transform)/INTT (Inverse NTT) circuit which generates cipher texts by performing a homomorphic multiplication calculation through transformation or inverse transformation of data, a cipher text multiplier which executes a multiplication calculation between the cipher texts, a cipher text adder/subtractor which executes addition and/or subtraction calculations between the cipher texts, and a rotator which performs a cyclic shift of a slot of the cipher texts.
