Abstract: A ferroelectric memory device and a semiconductor die are provided. The ferroelectric memory device includes a gate electrode; a channel layer, overlapped with the gate electrode; source/drain contacts, in contact with separate ends of the channel layer; a ferroelectric layer, lying between the gate electrode and the channel layer; and a first insertion layer, extending in between the ferroelectric layer and the channel layer, and comprising a metal carbonitride or a metal nitride.

Abstract: A fixing base is suitable to fix an electronic device having a locking hole. The fixing base includes a housing, a driving structure and a cam. The electronic device is suitable to be held in the housing. The driving structure is provided through the housing, and the cam is disposed in the housing. The cam has a hook, and the driving structure is fixedly connected to the cam. When the driving structure drives the cam to rotate, the hook is locked to the locking hole.

Abstract: A torsion spring assembly includes a torsion spring body and a fixed base. The torsion spring body has a first coil part and a second coil part. The first coil part connects to the second coil part. The fixed base has a first fixed arm and a second fixed arm. The first coil part is wound around the first fixed arm and the second coil part is wound around the second fixed arm. The winding direction of the first coil part is perpendicular to the winding direction of the second coil part. A portable electronic device with the torsion spring assembly is also disclosed.

Abstract: An assembling and dissembling mechanism for a data storage device suited to assemble and disassemble a data storage device in a casing having an opening includes a fastener having a connecting portion and a first fastening portion and a push button slidingly disposed at the opening of the casing. The connecting portion is fixed at the data storage device and is connected to the first fastening portion. The push button has a second fastening portion and a pushing portion which are disposed in the casing. The second fastening portion is suitable to be fastened with the first fastening portion to install the data storage device in the casing. When the push button slides by a predetermined distance, it drives the second fastening portion to be separated from the first fastening portion, and the pushing portion pushes the first fastening portion to disassemble the data storage device.
