Abstract
A power-on reading method of a memory device includes: generating a power-on signal according to a voltage level of a power voltage of the memory device; respectively detecting a plurality of ready states of a plurality of circuits in the memory device sequentially to generate a plurality of ready signals; reading a plurality of fuse states sequentially to generate a plurality of fuse state signals; and shifting a reference signal sequentially to generate a read pass indication signal according to the power-on signal, the plurality of ready signals and the plurality of fuse state signals by a plurality of registers coupled in series, wherein each of the plurality of registers is triggered when the power-on signal, corresponding ready signal or corresponding fuse state signal is at a setting logic value.
