Abstract
A memory device includes a memory array, a first reference unit, a second reference unit, and a control unit. The memory array includes a plurality of memory cells. The first reference unit provides a first reference current. The second reference unit provides a second reference current, wherein a current value of the first reference current is less than a current value of the second reference current. In a data-writing operation, the control unit provides a first current to a memory cell, reads a second current generated by the memory cell in response to the first current, and selects to compare the second current with the first reference current or to compare the second current with the second reference current according to a data-writing state of the memory cell, so as to determine whether a data writing of the data writing state is successful.
