    • An integrated circuit memory device includes a plurality of memory cells, a plurality of data lines, a memory cell selector, and a memory cell connector. The memory cells are arranged in a matrix of rows and columns wherein the plurality of memory cells are further grouped in banks with each bank including at least two rows of memory cells. Each of the data lines extends along one of the columns of memory cells so that each of the data lines extends along memory cells from each of the banks of memory cells. The memory cell selector includes a row decoder which selects one of the plurality of rows, a column decoder which selects one of the plurality of columns, and a bank decoder which selects one of the banks. The connector connects one of the memory cells to a respective data line in response to the memory cell selector. Accordingly, data from only one of the memory cells is provided on a respective one of the data lines at any point and time.

    • A semiconductor memory device includes input/output circuitry capable of operating in sync with an externally provided I/O clock signal. A data in buffer and a data out buffer provide for serial to parallel conversion of write data and, conversely, parallel to serial conversion of read data. The data buffers can be synchronized with the external I/O clock signal thereby decoupling their operation from the internal system clock signal. This strategy improves I/O bandwidth and further provides for matching different numbers of bit lines or word sizes as between the I/O data port and the memory array itself. An internal I/O clock generator can be provided for generating I/O clock signals, again without the limitation of synchronizing to the internal system clock signal.
    • 半导体存储器件包括能够与外部提供的I / O时钟信号同步操作的输入/输出电路。 缓冲器和数据输出缓冲器中的数据提供写入数据的串行到并行转换,相反地,并行读取数据的串行转换。 数据缓冲器可以与外部I / O时钟信号同步,从而将其操作与内部系统时钟信号分离。 该策略提高了I / O带宽,并进一步提供了在I / O数据端口和存储器阵列本身之间匹配不同数量的位线或字体大小。 可以提供内部I / O时钟发生器,用于产生I / O时钟信号,而不受与内部系统时钟信号同步的限制。

    • Example embodiments of the present invention include a memory device testable without using data and a dataless test method. The memory device includes a plurality of registers to store test patterns, the registers being coupled to input/output DQ pads. The test patterns are stored in the registers when a mode register of the memory device is set. The memory device transfers the test patterns to a DQ pad responsive to a write test signal, and transfers the test patterns from the DQ pad to a data input buffer responsive to a read test signal. The memory device writes the test patterns transferred to the data input buffer to memory cells. The memory device reads data stored in the memory cells responsive to the write test signal and transfers the memory cell data from the DQ pad to a comparator responsive to the read test signal. The memory device compares the test patterns to the memory cell data transferred to the comparator and generates an indicator signal to indicate the comparison result.
