Abstract:
A memory system according to the present invention includes a nonvolatile memory package and a memory controller controlling the nonvolatile memory package. The nonvolatile memory package includes nonvolatile memory devices which are connected to a plurality of internal data channels, respectively; and an I/O buffer circuit which connects a data channel to one of the internal data channels when data signals are inputted or outputted through the memory controller and the data channel.
Abstract:
PURPOSE: An oscillation circuit and a semiconductor device including the same are provided to stably stop an oscillation operation by inactivating a control signal in an inactive state of an oscillation enable signal. CONSTITUTION: An oscillation circuit includes a controller(1) and an oscillator(2). The controller includes a control signal generator and a reset signal generator. The oscillation unit generates a periodical signal with a constant pulse width by performing an oscillation operation for an active section of the control signal. The oscillation unit stops the oscillation operation by latching the periodical signal in the inactive state of the control signal. The oscillation unit outputs a first detection signal and a second detection signal for providing the inactive point of the control signal. The controller generates a control signal to control the oscillation operation of the oscillation unit in response to the first and second detection signals and the oscillation enable signal.
Abstract:
A majority voter circuit, data output circuit including majority voter circuit in semiconductor device is provided to perform the stable operation by using the decision circuit of the digital type. In a majority voter circuit, comparison unit(310) determines whether the number of same logic level of low rank N / 2 bit data is included in N bit data(D1-DN) is N / 2 or greater or not. A flag signal generator(320) generates a flag signal(FLAG) indicating whether N bit data having a plurality of the same logic level based on the decision results of the comparison unit. A flag signal generator generates the flag signal in response to the enable signal(EN) regardless of the enable signal.
