Abstract: A network control apparatus and method is provided. The method includes operations of informing a server of capability information including an encryption/decryption method, wherein the server provides the network control apparatus with control information used to control a network device using a general-purpose control web application, transmitting to the server a control information requesting message that requests the control information, receiving from the server the control information which has been encrypted using the encryption/decryption method, decrypting the encrypted control information according to the encryption/decryption method, and transmitting a control command for controlling the network device according to the decrypted control information.

Abstract: A semiconductor memory device having a selective error correction code (ECC) function is provided. The semiconductor memory device divides a memory cell array into blocks according to data retention characteristics of memory cells. A block in which there are a plurality of fail cells generated at a refresh rate of a refresh cycle that is longer than a refresh cycle defined by the standards of the semiconductor device is selected from among the divided blocks. The selected block repairs the fail cells by performing the ECC function. The other blocks repair the fail cells by using redundancy cells. Accordingly, a refresh operation is performed on the memory cells of the memory cell array at the refresh rate of the refresh cycle that is longer than the refresh cycle by the standards of the semiconductor device.
