MEMORY DEVICE, ERROR BIT DETECTOR AND ERROR BIT DETECTION METHOD THEREOF

The invention provides a memory device, an error bit detector and an error bit detection method thereof. The error bit detector comprises a current generator, a current mirror and a comparator. The current generator generates a first current according to a reference number. The current mirror generates a second current at a second end of the current mirror by mirroring the first current. The comparator compares a first voltage on the first input terminal with a second voltage on the second input terminal to generate a detection result. 本公开提供了一种存储器装置、错误位元侦测器及其错误位元侦测方法，该错误位元侦测器包括电流产生器、电流镜以及比较器。电流产生器根据参考数码以产生第一电流。电流镜通过镜射第一电流以在电流镜的第二端产生第二电流。比较器比较第一输入端上的第一电压与第二输入端上的第二电压以产生侦测结果。
