Abstract

A test operation method of a memory device includes a reference current generator generating a reference current and providing a reference voltage generated based on the reference current to one of input terminals of a sense amplifier; providing a read voltage generated based on a read current of a memory cell to another one of the input terminals of the sense amplifier; and the sense amplifier comparing the reference voltage with the read voltage.
