Method and apparatus for detecting strobe errors

摘要

A method and apparatus for detecting data strobe errors. A strobe error detection circuit has a strobe input and a counter coupled to the strobe input to count strobe pulses received. The circuit also has a comparator to determine if a strobe error has occurred based on the magnitude of the difference between a first count of strobe pulses and a second count of strobe pulses. In an embodiment, the first count is read from a memory location at a first time and the second count is read at a second time.
