  • 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: 20240072411
    Abstract: An electronic device includes a metal back cover, a metal frame, a first antenna module and a second antenna module. The metal frame includes a first and a second disconnection portion, a first and a second connection portion. The first and the second connection portion are connected to the metal back cover. The first disconnection portion is separated from the first connection portion, the metal back cover and the second disconnection portion to form a first slot. The second disconnection portion is connected to the second connection portion and is separated from the metal back cover to form a second slot. The first antenna module is connected to the first disconnection portion, and forms a first antenna path. The second antenna module is connected to the second disconnection portion, and forms a second and a third antenna path with the second disconnection portion and the metal back cover.
