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 time-of-flight sensor includes a substrate, a single photon avalanche detection chip, a vertical cavity surface-emitting laser, a first narrowband pass filter glass, and a second narrowband pass filter glass and a resin shell. The single photon avalanche detection chip is attached on the substrate, and the vertical cavity surface-emitting laser is also attached on the substrate. The first narrowband pass filter glass is arranged above the single photon avalanche detection chip, and the second narrowband pass filter glass is arranged above the vertical cavity surface-emitting laser. The resin shell covers the first narrowband pass filter glass and the second narrowband pass filter glass, and an upper surface of the first narrowband pass filter glass and an upper surface of the second narrowband pass filter glass are coplanar with an upper surface of the resin shell.

Abstract: The present disclosure is directed to an elastic polymer having characteristics of swelling by absorbing liquid and, and applications of preparation of gel electrolyte and absorbing the liquid by the polymer. The polymer is obtained by binding a poly(oxyethlene) L-NHm with a compound R being one elected from the group consisting of an acid, an anhydride and a combination thereof.
