Abstract: A resistive random-access memory (RRAM) device includes a bottom electrode, a high work function layer, a resistive material layer, a top electrode and high work function spacers. The bottom electrode, the high work function layer, the resistive material layer and the top electrode are sequentially stacked on a substrate, wherein the resistive material layer includes a bottom part and a top part. The high work function spacers cover sidewalls of the bottom part, thereby constituting a RRAM cell. The present invention also provides a method of forming a RRAM device.

Abstract: A size-adjustable sport shoe includes a shoe head, a shoe insole, and an adjusting telescopic device including a gear, a shaft gear, first and second gear racks, and handle. The first and second gear racks are located at two lateral sides of an elongated adjustment groove at the shoe head, wherein the upper surface of the second gear rack is lower than the upper surface of the first gear rack. The gear shaft is coupled between the gear and the handle. When the handle is folded perpendicularly to an axis direction of the gear shaft, the gear meshes with the first gear rack to lock up the shoe head at the shoe insole. When the handle is folded to coincide with the axis direction of the gear shaft, the gear meshes with the second gear rack to allow the shoe head to be slid from the shoe insole.

Abstract: The present invention provides a kind of skate, including a boot and a skating device connected to the boot, wherein the skating device is arranged along the width direction of the boot. The skate further includes a skating device mount for mounting the skating device to the boot, wherein the skating device can rotate 360 degree under the boot. The transverse skating device under the boot enables the sideward sliding direction, which bring more fun to the skaters. When the skating device is rotated to an angle and locked, the skate can slide inclinedly, which bring more challenges to the skaters. The skating device can rotate 360 degree freely or rotate different angle from two boots under the boot, which can cancel the shift of the knock-knee. The skating device can also be adjusted to be in line on the longitudinal direction as a traditional roller skate or ice skate.
