Semiconductor device
A semiconductor device includes: an interface chip including a read timing control circuit that outputs, in response to a command signal and a clock signal supplied from the outside, a plurality of read control signals that are each in synchronization with the clock signal and have different timings; and core chips including a plurality of internal circuits that are stacked on the interface chip and each perform an operation indicated by the command signal in synchronization with the read control signals. According to the present invention, it is unnecessary to control latency in the core chips and therefore to supply the clock signal to the core chips..

Synchronizer hub
The invention relates to a synchronizer hub (3) for a gearbox synchronization device (1) in a manual gearbox, comprising a base body (29) having a radial outer peripheral surface (30) and two axial end faces (31, 32) adjoining the circumferential surface (30), wherein an external tooth system (19) with radially outward pointing teeth (33) is arranged on the circumferential surface (30), interrupted by at least one recess (21), and with a annular groove (25), arranged in one of the end faces (32) and underneath the external tooth system (19), wherein the annular groove (25) is also interrupted by the at least one recess (21). Several segments (34) that extend in the radial direction into the area of the annular groove (25) and partially cover it are arranged on the axial end face (32)..
