A memory device, a host device and a method of operating the memory device are provided. The memory device includes a data signal generator configured to provide a data signal to a transmission driver, the transmission driver configured to output a multi-level signal having any one of first to third signal levels based on the data signal, a command decoder configured to receive a feedback signal from outside of the memory device and decode the feedback signal, a data signal controller configured to adjust the data signal based on a decoding result of the command decoder, and a drive strength controller configured to adjust at least one of the first to third signal levels based on the decoding result of the command decoder.

Memory device, host device and method of operating the memory device

A signal processing method of a semiconductor device, the method including: receiving a first digital code of a first digital signal; generating a constraint vector; masking the first digital code with a transmitting mask based on the constraint vector; and outputting the masked first digital code and a Data Bus Inversion (DBI) bit of the mask.

Signal encoding method and a semiconductor device to generate an optimal transition code in a multi-level signaling system

A data transmission method for transmitting a data signal using four data signal levels during a unit interval and transmitting a data bus inversion (DBI) signal using two DBI signal levels during the unit interval, the method including: receiving n (n is a natural number) data, each of the n data including a first bit and a second bit; counting the number of data in which the first bit and the second bit have the same value among the n data; in response to the counting result being less than or equal to a predetermined number, transmitting the n data using the four data signal levels, together with a DBI signal having a first DBI signal level; and in response to the counting result being greater than the predetermined number, transmitting data, which is obtained by changing a value of either of the first bit and the second bit of the n data, using the four data signal levels, together with a DBI signal having a second DBI signal level different from the first DBI signal level.

Data transmission method and a data transmission device

Provided are a data receiving device and a corresponding method for receiving the data. The data receiving device comprises a path control logic configured to store L symbol paths, where L is a natural number equal to or greater than 2, L feedback filters configured to calculate L inter-symbol interferences (ISI) for the L symbol paths, respectively, L operators configured to remove the L inter-symbol interferences from an output of a feed-forward equalizer, and a path metric calculator configured to receive outputs of the L operators and calculate a path metric for each of the L symbol paths, wherein the path control logic is configured to select L values among the calculated path metrics for the L symbol paths to update the L symbol paths.

Data receiving device and method

A retractor/pretensioner apparatus of a seatbelt for a vehicle may include a housing, a spool to which ends of a shoulder webbing and a wrap webbing may be simultaneously connected and which may be rotatably installed in the housing via a rotary shaft, a pinion coupled to one end of the rotary shaft, a first rack and a second rack slidably installed to the housing and engaged with the pinion respectively, a first gas generator fluid-connected to the first rack to provide gas to the first rack, and a second gas generator fluid-connected to the second rack to provide gas to the second rack.
