Abstract: A sharing system includes a sharing device arranged in a shared subject and a valet key that is allowed to operate the shared subject. The sharing system further includes a portable terminal that obtains key information required to use the shared subject and is allowed to operate the shared subject when the key information is authenticated through communication with the sharing device. The sharing system further includes a privilege granting unit that grants privilege to operate the shared subject from the portable terminal to the valet key, and a restriction imposing unit that imposes a restriction on use of the portable terminal when the operation privilege for the shared subject is granted from the portable terminal to the valet key.

Abstract: An on-board device includes a storage unit that stores personal information of a user registered to a vehicle, and a control unit that deletes the personal information of the user by controlling the storage unit when the vehicle has stayed at a certain location for a predetermined period.

Abstract: A bonded assembly includes a memory die including a three-dimensional memory array located on a first single crystalline semiconductor substrate, and a logic die including a peripheral circuitry located on a second single crystalline semiconductor substrate and bonded to the memory die. The three-dimensional memory array includes word lines and bit lines. The logic die includes field effect transistors having semiconductor channels configured to flow electrical current along a channel direction that is parallel to the bit lines or word lines. Different crystallographic orientations are used for the first and second single crystalline semiconductor substrates. The crystallographic orientations of the first single crystalline semiconductor substrate are selected to minimize stress deformation of the memory chip, while the crystallographic orientations of the second single crystalline semiconductor substrate are selected to maximize device performance of the peripheral circuitry.

Abstract: A three-dimensional memory device includes a vertical semiconductor channel surrounding a vertical dielectric core. Laterally extending dielectric pegs structurally support the vertical semiconductor channel and the vertical dielectric core. The vertical semiconductor channel may be a single crystalline semiconductor channel.

Abstract: Memory dies configured for multi-stacking within a bonded assembly may be provided without using through-substrate vias that extend through semiconductor substrates. A first memory die may be provided by forming interconnect-side bonding pads on a three-dimensional memory device that overlies a semiconductor substrate. A support die including a peripheral circuitry is boned to the interconnect-side bonding pads. The semiconductor substrate is removed, and array-side bonding pads are formed on an opposite side of the interconnect-side bonding pads. Electrically conductive paths that do not pass through any semiconductor material portion are formed between the interconnect-side bonding pads and the array-side bonding pads, thereby avoiding costly formation of through-substrate via structures that extend through any semiconductor substrate. A second memory die may be bonded to the first memory die to provide stacking of multiple memory dies.

Abstract: An on-board device includes a storage unit that stores biometric information of a user of a vehicle that is used for authentication, and a control unit that increases difficulty of authenticating biometric information not having been used for authentication for a predetermined period or deletes such biometric information from the storage unit.

Abstract: A vertically alternating stack of insulating layers and dielectric spacer material layers is formed over a semiconductor substrate. The vertically alternating stack is patterned into a first alternating stack located at a center region of a memory die and a second alternating stack that laterally encloses the first alternating stack. Memory stack structures are formed through the first alternating stack, and portions of the dielectric spacer material layers in the first alternating stack are replaced with electrically conductive layers while maintaining the second alternating stack intact. At least one metallic wall structure is formed through the second alternating stack. An edge seal assembly is provided, which includes at least one vertical stack of metallic seal structures. Each vertical stack of metallic seal structures vertically extends contiguously from a top surface of the semiconductor substrate to a bonding-side surface of the memory die, and includes a respective metallic wall structure.

Abstract: A fabrication process is provided for a 3D stacked non-volatile memory device which provides a source contact to a bottom of a memory hole in a stack without exposing a programmable material lining of an interior sidewall of the memory hole and without exposing a channel forming region also lining an interior of the memory hole to an energetic and potentially damaging etch environment. The stack includes alternating control gate layers and dielectric layers on a substrate, and the memory hole is etched through the stack before lining an interior sidewall thereof with the programmable material and then with the channel forming material. The process avoids a need to energetically etch down through the memory hole to open up a source contact hole near the bottom of the channel forming material by instead etching upwardly from beneath the memory hole.
