Abstract: A semiconductor device includes a stack structure including first electrodes and insulating layers alternately stacked on each other, a second electrode passing through the stack structure, and variable resistance patterns each interposed between the second electrode and a corresponding one of the first electrodes. Each of the first electrodes includes a first sidewall facing the second electrode, and each of the insulating layers includes a second sidewall facing the second electrode. At least a part of each of the variable resistance patterns protrudes farther towards the second electrode than the second sidewall.

Abstract: Disclosed is a method for automatically recovering data of an electronically erasable programmable read only memory (EEPROM) storing configuration information of a slave device by a programmable logic controller (PLC) communication module using an EtherCAT network when the data of the EEPROM is modified or incorrect.

Abstract: Disclosed is a method for variably changing a communication speed by a first device when a high-speed communication request within a range supported by the first device is input from a second device during low-speed communication of the first device with a third device in the UART communication and performing data communication with the second device at the varied high speed. A method for switching, by a device, a communication speed in an universal asynchronous receiver-transmitter (UART)-based data communication includes: measuring, by an interrupt detection module of the device, a pulse width of a start bit using an interrupt signal; calculating, by a communication speed calculation module of the device, a communication speed using a time duration for which the measured pulse width is maintained; and switching, by a communication speed switching module of the device, a current communication speed of the device to the calculated communication speed.

Abstract: An apparatus for converting terminal polarity for RS communication includes a comparator configured to discriminate polarities of a first signal line and a second signal line by comparing voltage levels indicated on the first and second signal lines of a cable for RS-485 communication, a switch unit configured to connect a TRXD+ terminal to the first signal line and connect a TRXD? terminal to the second signal line, or to connect a TRXD+ terminal to the second signal line or connect a TRXD? terminal to the first signal line in response to a provided switch control signal, and a switch controller configured to transmit the switch control signal to the switch unit in response to a polarity discrimination result by the comparator relative to the first signal line and the second signal line.

Abstract: A method for increasing formability of magnesium alloy sheet and the magnesium alloy sheet prepared by the same are provided, in which the method includes the following steps: forming {10-12} twins in magnesium alloy sheet (step 1); and annealing the magnesium alloy sheet of step 1 (step 2). The present invention also provides the magnesium alloy sheet containing {10-12} twins prepared by the method. Accordingly, the room temperature formability and the warm formability are increased by forming {10-12} twins through deformation on the magnesium alloy sheet and subsequently performing annealing, because it is possible to artificially form {10-12} twins without increasing dislocations in the magnesium alloy sheet and accommodate the deformation generated during the forming via annihilation of the twins.
