A virtual device control method of a computing device which includes a nonvolatile memory is provided. The virtual device control method includes receiving a virtualization request; assigning a first part of the nonvolatile memory to a virtual memory; assigning a second part of the nonvolatile memory to a virtual storage; and generating a virtual device including the assigned virtual memory and virtual storage.

Computing device and virtual device control method for controlling virtual device by computing system

Provided is a method of preventing simultaneous activation of redundancy memory line or spare word lines, the method including: programming a fail address of a memory line determined to be defective; reprogramming the fail address if a first spare line for the memory line is determined to be defective; storing additional information with respect to the reprogrammed fail address; and activating a second spare line and inactivating the first spare line, referring to the additional information.

Post package repairing method, method of preventing multiple activation of spare word lines, and semiconductor memory device including fuse programming circuit

A nonvolatile memory is provided which includes a memory cell array including a plurality of nonvolatile memory cells; a decoder connected with the memory cell array through a plurality of word lines; a data input/output circuit connected with the memory cell array through a plurality of bit lines; a voltage detector configured to detect a variation in a power supply voltage to output a voltage variation signal; and control logic configured to control the decoder and the data input/output circuit such that data stored at the memory cell array is invalidated in response to the voltage variation signal.
