Abstract
A dynamic random-access memory (DRAM) device is provided. The DRAM device includes slave DRAM chips and a master DRAM chip. Each of the slave DRAM chips includes a slave reference voltage pad, a slave voltage sensor, a slave voltage pump and a slave fuse circuit. The slave voltage sensor senses a voltage value of a reference voltage on the slave reference voltage pad and provides a slave oscillating signal according to the voltage value of a reference voltage on the slave reference voltage pad. The slave voltage pump provides the reference voltage according to the slave oscillating signal. The slave fuse circuit provides a slave set signal according to a slave fuse setting operation of the slave fuse circuit and disables the slave voltage sensor according to the slave set signal. The master DRAM chip controls operations of the slave DRAM chips.
