Abstract
An apparatus for controlling memory includes a memory controller, and a data interface that interfaces with and is in data communication with data lines, each having inherent skew. Each data line carries a data signal. The data lines connect the memory controller to the memory. The apparatus also includes data de-skewers, each associated with a corresponding data line, a strobe interface that interfaces with a strobe line that connects the memory controller to the memory and that applies a timing signal to the strobe line, and a strobe de-skewer connected to the strobe line. Each data de-skewer operates in read or write mode. A particular data line's data de-skewer applies a compensation skew to a data signal carried by that line.
