A memory device includes an input unit configured to receive a plain text and output plain blocks and CTS plain block, a multi-core unit including a plurality of encryption/decryption cores configured to encrypt each of the plain blocks provided from the input unit and output cipher blocks in accordance with control of an encryption/decryption core control unit, a CTS core unit including a CTS core configured to encrypt the CTS plain block provided from the input unit into a CTS cipher block, and an output unit configured to receive the cipher blocks and the CTS cipher block and output a cipher text. The CTS plain block is generated through a CTS calculation based on the plain text.

Memory device and method for data encryption/decryption of memory device

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.
