Abstract:
A method of calibrating read operations in a memory system is disclosed. The method involves placing a memory controller in a calibration mode, and performing a series of dummy read operations. Each of the read operations performs a read of pre-specified data stored in at least one memory component while using different ones of delayed enable signals. Data read from respective dummy read operations is compared to identify successful read operations while the timing information from successful read operations is compared to identify a suitable delayed enable signal.
