  • Patent number: 11966628
    Abstract: A memory device, includes a memory array for storing a plurality of vector data each of which has an MSB vector and a LSB vector. The memory array includes a plurality of memory units each of which has a first bit and a second bit. The first bit is used to store the MSB vector of each vector data, the second bit is used to store the LSB vector of each vector data. A bit line corresponding to each vector data executes one time of bit-line-setup, and reads the MSB vector and the LSB vector of each vector data according to the bit line. The threshold voltage distribution of each memory unit is divided into N states, where N is a positive integer and N is less than 2 to the power of 2, and the effective bit number stored by each memory unit is less than 2.

  • Publication number: 20240096830
    Abstract: A method includes forming a first sealing layer at a first edge region of a first wafer; and bonding the first wafer to a second wafer to form a wafer stack. At a time after the bonding, the first sealing layer is between the first edge region of the first wafer and a second edge region of the second wafer, with the first edge region and the second edge region comprising bevels. An edge trimming process is then performed on the wafer stack. After the edge trimming process, the second edge region of the second wafer is at least partially removed, and a portion of the first sealing layer is left as a part of the wafer stack. An interconnect structure is formed as a part of the second wafer. The interconnect structure includes redistribution lines electrically connected to integrated circuit devices in the second wafer.

  • Publication number: 20240085921
    Abstract: A system for obstacle detection adapted to a self-guiding machine is provided. The system includes a controller, a linear light source and a light sensor. The linear light source and the light sensor are set apart at a distance. When the linear light source emits an indicator light being a vertical linear light projected onto a path the self-guiding machine travels toward, the light sensor senses the indicator light. The vertical linear light is segmented into a first segment projected to a ground and a second segment projected to a floating obstacle when the self-guiding machine approaches the floating obstacle with a height from the ground and the indicator light is projected to the floating obstacle, in which the second segment of the light sensed by the light sensor is determined as the floating obstacle in front of the self-guiding machine.
