    摘要: Provided are a semiconductor memory device and a method of programming the same. The semiconductor memory device includes a mode input value generating unit and a logic operating unit. The mode input value generating unit changes a connection state between input values of a current driving circuit so as to correspond to each of at least two operating modes, and defines a logic function of a magnetic memory cell connected to the current driving circuit in response to each operating mode. The logic operating unit performs a logic operation on the logic functions of at least two magnetic memory cells defined according to each of the operating modes and generates a result of logic operation.

    摘要: Oscillators and methods of manufacturing and operating the same are provided, the oscillators include a pinned layer, a free layer and a barrier layer having at least one filament between the pinned layer and the free layer. The pinned layer may have a fixed magnetization direction. The free layer corresponding to the pinned layer. The at least one filament in the barrier layer may be formed by applying a voltage between the pinned layer and the free layer. The oscillators may be operated by inducing precession of a magnetic moment of at least one region of the free layer that corresponds to the at least one filament, and detecting a resistance change of the oscillator due to the precession.
