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: An electronic device and a component module thereof are provided, wherein the electronic device includes a housing, a component and a flexible substrate. The housing has a mounting region, and the component is disposed in the mounting region. The flexible substrate includes a bonding portion and an extending portion, wherein the bonding portion is disposed between the component and a carrying surface of the mounting region. The mounting portion has a first surface and a second surface opposite to the first surface, wherein the first surface is bonded to the component, and the second surface is bonded to the carrying surface. The extending portion is connected to the bonding portion and extended to the outside of the mounting region.

Abstract: A receptacle connector is provided for connection with a plug having two hooks. The receptacle connector includes a first tongue segment, a second tongue segment, and a housing forming an opening and two holes. The first and second tongue segments are disposed in the housing and opposite to each other. The first tongue segment includes a main body, a plurality of first contacts and two stoppers, wherein the two stoppers are located at opposite sides of the contacts and fixed to the main body. When the plug is inserted into the housing through the opening with a normal posture, the hooks are engaged in the holes. When the plug is wrongly inserted into the housing with an inverted posture (upside down), the stoppers obstruct the hooks to prevent insertion of the plug.

Abstract: A keyboard module (300) includes a printed circuit board (302), a Qwerty keyboard (304) mounted on the printed circuit board. A plurality of application buttons (308) mounted on the printed circuit board and located within the Qwerty keyboard, and a navigator button (306) mounted on the printed circuit board and located also within the Qwerty keyboard. The navigator button has four direction buttons (316a, 316b, 316c, 316d) each having a profile higher than that of keys of the Qwerty keyboard. Each of four keys of the Qwerty keyboard neighboring the navigator button is located between two neighboring direction buttons of the navigator button.

Abstract: A latch structure for a mobile electronic device (1), for example, a personal digital assistant (PDA) is disclosed. The latch structure comprises a side flange (20) of a cover (10) and a side panel (30). The side flange (20) includes a cantilever (200) and at least a first engaging portion (205). The cantilever has a slanted face (201) and a lock (203) on a free end thereof. The lock has a first ramp (207). The side panel detachably connects to the side flange and defines a hole (301). The side panel includes a second engaging portion (303) and a third engaging portion (305). The hole corresponds to the slanted face. The second engaging portion has a second ramp (307) corresponding to the first ramp of the lock. The lock engages with the second engaging portion in a first position and disengages from the second engaging portion in a second position. The first engaging portion engages with the third engaging portion in the first position and disengages from the third engaging portion in the second position.

Abstract: A Personal Digital Assistant (PDA) with retractable stylus comprises a retractable stylus, a housing, a stylus slot, and a push portion, wherein a contact pad is attached to the inner side of the push portion. The retractable stylus comprises a pen shaft having a release button, a pen body having an opening, and a spring situated inside the pen body. When an external force is applied to the pen shaft downward, the spring is compressed until the opening holding the release button; thus, the stylus is shortened. When the release button is set free from the opening, the spring elasticity ejects the pen shaft upward; thus, the stylus returns to the full-length condition. If the stylus is kept in the stylus slot, an external force applied to the push portion can make the contact pad press the release button; so the pen shaft is ejected upward by spring elasticity.
