    摘要: A method and apparatus for tuning a phase of a data clock signal having a different frequency than a main clock signal. The method of tuning includes coarse tuning by receiving the data clock signal, dividing the data clock signal to generate a frequency-divided clock signal having a same frequency as the main clock signal, repeatedly shifting the frequency-divided clock signal to generate multiphase frequency-divided clock signals at a predetermined phase interval, comparing a phase of each of the multiphase frequency-divided clock signals with a phase of the main clock signal, and determining a phase shift amount based on a comparison result, and fine tuning by comparing a phase of a multiphase frequency-divided clock signal corresponding to the phase shift amount with the phase of the main clock signal and adjusting the phase of the data clock signal by a predetermined phase step based on the comparison result.

    摘要: Provided is a semiconductor memory device including a column decoder, a plurality of sub-cell blocks, and a bit line selection circuit. The column decoder is configured to decode column addresses and drive column selection signals. Each of the sub-cell blocks includes a plurality of bit lines, a plurality of word lines, and a plurality of memory cells connected to the plurality of bit lines and the plurality of word lines. The bit line selection circuit includes a plurality of bit line connection controllers, and is configured to select one or more bit lines in response to the column selection signals. Each of the bit line connection controllers electrically couples a respective first bit line to corresponding first and second local input/output (I/O) lines in response to first and second column selection signals of the column selection signals, respectively.
