Abstract: A memory module includes a circuit board, a plurality of memory devices, and a power management integrated circuit (PMIC). The circuit board includes first connectors, a second connector, and a third connector connected to an external device. The plurality of memory devices are mounted on the circuit board, and connected to the first connectors. The PMIC receives a first voltage through the second connector, generates a second voltage using the first voltage, and provides the second voltage to the plurality of memory devices The PMIC adjusts the second voltage based on a signal received through the third connector such that a voltage difference of the first voltage and the second voltage is reduced in a training mode of the memory module.

Abstract: A method of operating a memory system includes setting a secured area in a volatile memory device of the memory system during a secure mode, writing secure data in the secured area during the secure mode, and when a write command for the secured area is inputted in a normal operation mode, preventing a write operation from occurring and generating an error signal. Accordingly, the secured area is set in the volatile memory device so that the hacking and the data forgery may be prevented.

Abstract: A memory module includes semiconductor memory devices, a power management integrated circuit (PMIC), and a control device. The semiconductor memory devices, mounted on a circuit board, operate based on a power supply voltage. The PMIC, mounted on the circuit board, generates the power supply voltage, provides the power supply voltage to the semiconductor memory devices, and stores a trimming control code associated with a minimum level of the power supply voltage when the semiconductor memory devices operate normally in a test mode. During the test mode, the PMIC adjusts a level of the power supply voltage, tests the semiconductor memory devices using the adjusted power supply voltage, and stores the trimming control code based on a result of the test. The control device controls the PMIC based on a first control signal received from an external device.
