Abstract: A system includes a fuse pump; a fuse that can be blown by the fuse pump; and a voltage source configured to provide a first voltage only if the fuse pump is enabled to blow the fuse, the fuse pump blowing the fuse when the first voltage serves as a supply voltage of the fuse pump. If the first voltage serves as a supply voltage of the fuse pump, a first consumed time is required to blow the fuse. If a second voltage, provided by the voltage source, were to be served as a supply voltage of the fuse pump, a second consumed time is required to blow the fuse. The first consumed time is less than the second consumed time.

Abstract: A voltage system and a method of operating a voltage system are provided. The voltage system includes an oscillator and a pump device. The oscillator is configured to provide an oscillation signal exhibiting a first frequency when a voltage level of a supply voltage is greater than a reference voltage level, and to provide the oscillation signal exhibiting a second frequency greater than the first frequency when the voltage level of the supply voltage is less than the reference voltage level. The pump device is configured to provide the supply voltage, based on a frequency of the oscillation signal provided by the oscillator, by performing a charging operation.

Abstract: The present disclosure provides a pump system of a DRAM and a method for operating the same. The pump system includes a pump device and a spare pump assembly. The pump device provides a current sufficient to allow a bank of the DRAM to operate at a normal refresh rate without other spare pump devices in response to a normal instruction which indicates that the bank is instructed to operate at the normal refresh rate. The spare pump assembly includes a first spare pump device configured to provide, in combination with the pump device, a current sufficient to allow the bank to operate at a first refresh rate greater than the normal refresh rate in response to a first instruction which indicates that the bank is instructed to operate at the first refresh rate.

Abstract: The present disclosure provides a dynamic random access device (DRAM). The DRAM includes a first node, a second node and a pad. The first node is configured to conduct a first internal signal generated by internal devices of the DRAM. The second node is configured to conduct a second internal signal generated by other internal devices of the DRAM. The pad is configured to receive one of the first internal signal and the second internal signal.
