摘要:
A semiconductor memory device is provided that is capable of increasing a data processing speed and the efficiency of a data input and output pin. A method is also provided for controlling the read and write of such a device. A data first-in first-out (FIFO) circuit temporarily stores write data when a read command is received during a write operation and outputs the stored write data to the memory cell array after a read operation is completed. An address FIFO circuit temporarily stores addresses corresponding to the write data when the read command is received during the write operation and outputs the stored addresses to the memory cell array after the read operation is completed. A control signal generator generates a plurality of control signals for controlling the data FIFO circuit and the address FIFO circuit in response to a write command and the read command. When the addresses received during the read operation coincide with the addresses stored in the address FIFO circuit, data is not output from the memory cell array, but instead, the write data stored in the data FIFO circuit is output. The number of write data items stored in the data FIFO circuit and the number of addresses stored in the address FIFO circuit vary according to the column address strobe (CAS) latency of the semiconductor memory device.

Wireless communication system and wireless communication method using a wireless channel. A transmitting device changes one of a data bitrate of a video signal and an actual transmission rate of the video signal based on a determination of a maximum transmission throughput of the wireless channel and transmits the video signal over the wireless channel according to the change in the data bitrate or the change in the actual transmission rate. A receiving device receives, temporarily stores, and decodes the video signal transmitted over the wireless channel. Thus, the wireless communication system is capable of maintaining a continuous video display when a discontinuous video signal is transmitted over the wireless channel.

In a method of wirelessly transmitting an audio and/or video input signal having a standard definition (SD), the input signal is converted to a signal having a high definition (HD) and noise is removed from the converted signal. High definition encoding is performed to the noise-free signal and the encoded signal is wirelessly transmitted. Accordingly, image deterioration can be reduced by eliminating the noise before encoding the input signal. In addition, the HD encoding is performed instead of the SD encoding to reduce image degradation.

Current sense amplifiers include a pair of differential output signal lines and a current sensor electrically coupled to the pair of differential output signal lines. A first equalization device is also provided. The first equalization device is electrically coupled to the pair of differential output signal lines and is responsive to a sense amplifier enable signal (SAEN). In addition, according to a preferred aspect of the present invention, a second equalization device is also provided to reduce the likelihood that the differential outputs of the current sense amplifier will oscillate during sense and amplify operations. This second equalization device is also electrically coupled to the pair of differential output signal lines, however, the second equalization device is not responsive to the sense amplifier enable signal. Instead, the second equalization device is preferably responsive to a power supply signal (e.g., Vcc) and/or reference signal (e.g., Vss) and performs a constant or variable equalization function when the sense amplifier is active.

An apparatus and method of protecting content from a third party in a communication system including a wired section and a wireless section. The content transferred through the wired section is scrambled separately from a transfer through the wireless section. A controller of a sending end determines scrambling algorithms and a scrambling order to be used in the wired section, and provides related information to a controller of a receiving end. The sending end scrambles the content according to the scrambling algorithms and order. The receiving end descrambles the content by use of the provided related information.
