  • Patent number: 11978511
    Abstract: A phase-change memory (PCM) cell is provided to include a first electrode, a second electrode, and a phase-change feature disposed between the first electrode and the second electrode. The phase-change feature is configured to change its data state based on a write operation performed on the PCM cell. The write operation includes a reset stage and a set stage. In the reset stage, a plurality of reset current pulses are applied to the PCM cell, and the reset current pulses have increasing current amplitudes. In the set stage, a plurality of set current pulses are applied to the PCM cell, and the set current pulses exhibit an increasing trend in current amplitude. The current amplitudes of the set current pulses are smaller than those of the reset current pulses.

  • Publication number: 20240128420
    Abstract: A display panel including a circuit board, a plurality of bonding pads, a plurality of light emitting devices, and a plurality of solder patterns is provided. The bonding pads are disposed on the circuit board, and each includes a first metal layer and a second metal layer. The second metal layer is located between the first metal layer and the circuit board. The first metal layer includes an opening overlapping the second metal layer. A material of the first metal layer is different from a material of the second metal layer. The light emitting devices are electrically bonded to the bonding pads. Each of the solder patterns electrically connects one of the light emitting devices and one of the bonding pads. The solder patterns each contact the second metal layer through the opening of the first metal layer of one of the bonding pads to form a eutectic bonding.

  • Patent number: 11683753
    Abstract: A wireless transmission system comprises an antenna component, a wireless module including a processing unit and a power controlling unit, a tuner connected between the antenna component and the wireless module, and a sensor connected to the wireless module. The tuner is configured to adjust an output bad of the power controlling unit according to a received signal strength indication of the wireless transmission system being greater than a predetermined threshold value, such that multiple different load values are provided for the power controlling unit. The sensor is configured to detect and record a current consumption value corresponding to each load value. In response to the wireless module emitting signals via the antenna component, the processing unit selects the load value corresponding to the lowest of the current consumption values and applies the selected load value to the output load of the power controlling unit.
