Samsung patents memory controller that fine-tunes data reading
Samsung describes a memory system where the controller uses a training circuit to improve data accuracy. It creates multiple shifted versions of a test pattern and compares them to the incoming signal to find the best timing for reading data.
In the filing’s own words
According to some example embodiments, a memory system includes a memory device, and a memory controller configured to control the memory device, the memory controller including a training circuit, the training circuit configured to generate a plurality of reference pattern data, the plurality of reference pattern data including a plurality of pieces of reference pattern data, the plurality of pieces of reference pattern data generated by cyclically shifting basic pattern data in units of unit intervals, generate a comparison result by simultaneously comparing the plurality of reference pattern data to sampling data, and calculate a center of a window of a data signal based on the comparison result.
What exactly they claim (claim 1)
1. A memory system, comprising: a memory device; and a memory controller configured to control the memory device, the memory controller including a training circuit, the training circuit configured to, generate a plurality of reference pattern data, the plurality of reference pattern data including a plurality of pieces of reference pattern data, the plurality of pieces of reference pattern data generated by cyclically shifting basic pattern data in units of unit intervals; generate a comparison result by simultaneously comparing the plurality of reference pattern data to sampling data; and calculate a center of a window of a data signal based on the comparison result.
