Abstract: A memory expander includes memory sub-modules, power management integrated circuits, a controller, and a power controller. The memory sub-modules store data, and each of the memory sub-modules includes one or more memories. The power management integrated circuits independently supply powers to the memory sub-modules, respectively. The controller communicates with an external device through an interface (e.g., compute express link (CXL)), controls operations of the memory sub-modules, and checks whether the memory sub-modules are abnormal. The power controller controls operations of the power management integrated circuits. In response to a first memory sub-module becoming abnormal, the power controller controls a first power management integrated circuit to block a first power supplied to the first memory sub-module.
