Abstract
A system includes memory unit having one or more storage arrays, and a memory interface unit that may be coupled between a memory controller and the memory unit. The memory interface unit may include a timing unit that may generate timing signals for controlling read and write access to the memory unit, and a control unit that may calibrate the timing unit at predetermined intervals. However, in response to an occurrence of a given predetermined interval, the memory interface unit may be configured to calibrate the timing unit using a number of partial calibration segments.
