  • REAR SEAT APPARATUS FOR VEHICLE
    Publication number: 20250091493
    Abstract: A rear seat apparatus for a vehicle includes a back frame and a cushion frame. The back frame is not interlocked with the cushion frame and is individually rotated in the forward-and-rearward direction independently of the cushion frame. The cushion frame is not interlocked with the back frame and individually slides in the forward-and-rearward direction independently of the back frame. A front seating state and a rear seating state of a passenger are implemented through individual sliding movement of the cushion frame in the forward-and-rearward direction.

  • LDPC decoder, semiconductor memory system and operating method thereof
    Patent number: 10997021
    Abstract: A semiconductor memory system including: a semiconductor memory device suitable for storing a codeword; and an LDPC decoder suitable for decoding the codeword to generate decoded data, wherein the LDPC decoder includes: a message passing decoding component suitable for performing a first decoding operation of decoding the codeword, and calculating the minimum value among numbers of UCNs; and an error path detection component suitable for detecting error path candidates using a tree in which each of UCNs corresponding to the minimum value is set to a root node, sorting the detected error path candidates in ascending order of maximum LLRs, resetting symbol values and LLRs of variable nodes in the error path candidates, and providing the message passing decoding unit with information on the reset symbol values and LLRs.
