Abstract
A method for data acquisition in a memory system includes oversampling a data signal and a strobe signal with a multiphase clock having n phases to generate a series of data signals and a series of strobe signals representing a first data series and a first strobe series respectively, generating a second strobe series by edge detection of the first strobe series followed by retiming of the edge detected series, generating a third strobe series by edge adjustment of the second strobe series, wherein the edge adjustment ensures that there are no overlapping edges among the signals of the third strobe series, generating a sample selected series by linear shifting of each signal of the third strobe series by n/2, generating a second data series by retiming the first data series, generating a third data series by sample adjustment of the second data series, wherein the sample adjustment ensures that the third data series is in synchronization with a sampling window of the sample selected series, and determining a final data signal by multiplexing the third data series with the sample selected series.
