DETECTING APPARATUS OF SEMICONDUCTOR MEMORY APPARATUS

摘要

PURPOSE: A detecting apparatus of a semiconductor memory apparatus is provided to help a user to easily analyze to solve a MRD fail by securing the generation of a plurality of column select signals. CONSTITUTION: In a detecting apparatus of a semiconductor memory apparatus, a normal activity determining unit(100) confirms the activation of a normal column signal and generates a normal confirmation signal. The repair activity determining unit(200) confirms the activation of a repair column select signal and generates a repair confirmation signal. A plurality of activity determining units(300) generate plural column active signal according to the normal confirmation signal and the repair confirmation signal.
