A memory device includes a command decoder that implements security logic to detect a command sequence to read a security region of a memory array with continuous encrypted data and to output/input specific contexts for the data. Output/input of specific contexts can be during a dummy cycle to achieve greater performance. A host interfacing can, for example, execute a single command to both get the encrypted data and specific contexts that were used to encrypt the data. Our technology can implement transferring data on the system bus in ciphertext and encrypted by a different Nonce or a different session key than used in a previous transfer operation. In this way, data will be represented with different ciphertext on the bus at different sessions; thereby defending against a replay attack.

The sensing module includes a sensing amplifier and a current sink, and both are electrically connected to the memory cell. The sensing amplifier generates a sensing current and identifies the un-programmed/programmed state of the memory cell accordingly. The current sink receives a reference current being equivalent to the summation of the sensing current and a cell current flowing through the memory cell. The reference current is constant, and the sensing current is changed with the cell current. The cell current is generated based on a high read voltage and a low read voltage applied to the memory cell. The sensing current is higher if the memory cell is un-programmed, and the sensing current is lower if the memory cell is programmed.
