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.

摘要： 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.

摘要： 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.
