Abstract: A memory array and an operation method of the memory array are provided. The memory array includes first and second ferroelectric memory devices formed along a gate electrode, a channel layer and a ferroelectric layer between the gate electrode and the channel layer. The ferroelectric memory devices include: a common source/drain electrode and two respective source/drain electrodes, separately in contact with a side of the channel layer opposite to the ferroelectric layer, wherein the common source/drain electrode is disposed between the respective source/drain electrodes; and first and second auxiliary gates, capacitively coupled to the channel layer, wherein the first auxiliary gate is located between the common source/drain electrode and one of the respective source/drain electrodes, and the second auxiliary gate is located between the common source/drain electrode and the other respective source/drain electrode.

Abstract: A wound treatment system includes a wound dressing, a negative-pressure source, a light-emitting device, an image recognition module, and a control module. The wound dressing includes a housing with an opening, and a barrier layer with a conduit pathway separating the inside of the housing from the opening to form a receiving space. The negative-pressure source is fluidly connected to the wound dressing to remove tissue exudate of the wound. The light-emitting device is disposed in the receiving space, optically coupled to the barrier layer and can emit light of different wavelength bands as the detection light required by the image recognition module disposed on a side of the opening of the housing of the wound dressing and provide specific wavelengths of phototherapy required by different stages of the wound.
