ABSTRACT:
Memory circuits are calibrated by adjusting memory circuit output parameters based on data eye measurements. Data eye patterns of memory circuit outputs are measured by the memory controller for different settings of the memory circuit output parameters. Memory circuit output parameters can be adjusted to settings that correspond to widest average data eye widths, highest average data eye heights, or other suitable criteria.
