Disclosed is a LiDAR window integrated optical filter that includes a window of a polymer material for absorbing a visible light band and transmitting a near-infrared band; and an upper reflective layer and a lower reflective layer formed on the upper surface and the lower surface of the window. The upper reflective layer and the lower reflective layer may be formed in a thin film including titanium dioxide (TiO) and silicon dioxide (SiO).

LiDAR window integrated optical filter

An operating method of a controller that includes: when a first ECC decoding on data read from a semiconductor memory device according to a hard read voltage fails, generating one or more quantization intervals based on the number of unsatisfied syndrome check (USC), which is a result of the first ECC decoding; and performing a second ECC decoding on the data by generating soft read data according to soft read voltages determined by the hard read voltage and the quantization intervals.

Controller, semiconductor memory system and operating method thereof

An operating method of a controller includes iterating a first ECC decoding on a codeword read from a semiconductor memory device according to a first read voltage a predetermined iteration number until the first ECC decoding succeeds, wherein a value of the first read voltage is updated on basis of a number of an unsatisfied syndrome check (USC); and when the first ECC decoding fails until the predetermined iteration number, performing a second ECC decoding on the codeword by generating soft decision data according to the first read voltage, a value of which corresponds to the minimum number of the USC among the updated values during the iterating of the first ECC decoding.
