  • Publication number: 20250258738
    Abstract: A memory device, a memory system, and a method of operating the same. The memory device includes a memory cell array including a plurality of memory cells and a write command determination unit (WCDU) that determines whether a write command input to the memory device is (to be) accompanied a masking signal. The WCDU produces a first control signal if the input write command is (to be) accompanied by a masking signal. A data masking unit combines a portion of read data read from the memory cell array with a corresponding portion of input write data corresponding to the write command and generates modulation data in response to the first control signal. An error correction code (ECC) engine generates parity of the modulation data.

  • Patent number: 9646718
    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.

  • Patent number: 9281959
    Abstract: A method of controlling a home network device by using a universal web application. In the method, the universal web application may receive control information, for controlling the home network device, from a server. A control command, which is issued to control the home network device, may be sent to a control point module by using a script application program interface (API) that is included in the received control information. Accordingly, result data that is obtained by executing the control command on the home network device may be received by the control point module.
