  • Optical element driving mechanism having movable portion for holding lens
    Patent number: 11982866
    Abstract: An optical element driving mechanism is provided and includes a fixed assembly, a movable assembly, a driving assembly and a stopping assembly. The fixed assembly has a main axis. The movable assembly is configured to connect an optical element, and the movable assembly is movable relative to the fixed assembly. The driving assembly is configured to drive the movable assembly to move relative to the fixed assembly. The stopping assembly is configured to limit the movement of the movable assembly relative to the fixed assembly within a range of motion.

  • Datapath architecture for high area efficiency
    Patent number: 7054178
    Abstract: A particular DRAM data path architecture is disclosed. In accordance with this invention, the sharing of MDQ sense amplifiers simplifies the circuit design of the memory sub array. Fewer MDQ sense amplifiers and fewer unique MDQ lines leads to a reduced chip layout area. The high address bit of the word line row address (RA) is used to select a particular main data sense amp by means of a control switch. Not only are the sense amplifiers multiplexed for the new sub array, but the data I/O are multiplexed as well, leading to a significant reduction in the number of circuits required.
