Abstract:
An apparatus and method for assigning a Physical Cell Identity (PCI) of a Home eNodeB (HeNB) are provided. The apparatus may distribute PCIs into a plurality of PCI groups, and may enable a PCI group to be assigned to a cell so that the assigned PCI group may be different from a PCI group assigned to a neighboring cell, and that an unassigned PCI in the assigned PCI group may be assigned to an HeNB within a single cell.
Abstract:
A semiconductor memory device having a data read path maintains a higher power voltage supplied to an input/output sense amplifier in the input/output path, through which data passes during a data read operation, than the voltage supplied to other circuit components in the data read path, thereby achieving a high data read speed.

Abstract:
A buffer includes a pull-down means, a pull-up means, and a control signal generator. The pull-down means generates an output signal that transitions to a first state at a relatively high speed when an input signal transitions from a first state to a second state in response to a control signal at a first control state. The pull-up means generates an output signal that transitions to the second state at a relatively high speed when an input signal transitions from the second state to the first state in response to a control signal of a second control state. The control signal generator produces the control signal as a function of the output signal. Accordingly, the buffer can transfer an input signal at a high speed in both cases of a high-to-low transition of the input signal as well as a low-to-high transition of the input signal.

Abstract:
An application component communication method and an apparatus using the same are provided to an SCA-based system for efficiently performing data communication between SCA-based application components by using a dynamic connection manager. The application component communication apparatus includes an application module provided in the SCA-based system and driven, an application packaged by a plurality of application components, and an application factory for generating the application and driving the application components by parsing XML files. The dynamic connection manager registers port information of each of the application components, and establishes a connection for data communication between the application components according to the port information. According to the present invention, data communication between the respective application components can be efficiently performed by using the dynamic connection manager.
Abstract:
A semiconductor memory device capable of improving common bus efficiency is disclosed. The device comprises an address shifting circuit for delaying an address by an n+m number of clock cycles in response to a clock signal, a control signal generating circuit for combining a column address strobe (CAS) latency of n-value and one of first and second operation signals to generate a control signal, and a switching circuit for outputting the address delayed by the n+m number of clock cycles output from the address shifting circuit in response to the control signal. The first operation signal indicates that the n-value of the CAS latency is less than a predetermined value and write latency is fixed. The second operation signal indicates that the n-value of the CAS latency is equal to or greater than the predetermined value and the write latency is variable.
