Apparatus and method for pre-analyzing memory fault information

A memory fault information pre-analysis method of a memory fault information pre-analysis apparatus including a fault monitor, a fault counter, a must monitor, and a fault address collector, the method comprising:

• (a) receiving fault data configured by a row address and a column address of a memory;
• (b) storing a location where fault information about the fault data is to be stored in the fault counter, the must monitor, and the fault address collector in the fault monitor;
• (c) storing a number of faults in a fault row and a fault column of the memory in the fault counter;
• and
• (d) storing must fault information in the must monitor and a row address and a column address of the fault data and whether it is a pivot fault in the fault address collector.
