Abstract
A method of operating a system running a virtual machine that executes an application and an operating system (OS) includes performing first address translation from first virtual addresses to first physical addresses, identifying faulty physical addresses among the first physical addresses, each faulty physical address corresponding to a corresponding first physical address associated with a faulty memory cell, analyzing a row address and a column address of each faulty physical address and specifying a fault type of the faulty physical addresses based on the analyzing of the row address and the column address of each faulty physical address, and performing second address translation from second virtual addresses to second physical addresses based on a faulty address, thereby excluding the faulty address from the second physical addresses.
