Abstract
Methods, apparatuses, and systems related to operations for measuring the quality of a signal received by a memory device and providing feedback. The memory device can sample signal data using a predetermined sequence of timing offsets relative to a reference signal. Additionally or alternatively, the memory device can sample the signal data using a predetermined sequence of reference voltages. The memory device can provide feedback results to a controller regarding the quality of the sampled signal data.
Claims20
An apparatus, comprising:
- a logic circuit configured to:
- generate first sampling results based on sampling a first predetermined data pattern from a controller using a first setting;
- and
- generate second sampling results based on sampling a second predetermined data pattern from the controller using a second setting;
- and
- a communication circuit coupled to the logic circuit and configured to send the first sampling results and the second sampling results to the controller for adjusting a setting associated with subsequently communicated signals.

A memory system, comprising:
- a memory controller;
- a memory array operably coupled to the memory controller and configured to:
- generate first sampling results based on sampling a first predetermined signal pattern from the memory controller using a first setting;
- generate second sampling results based on sampling a second predetermined signal pattern from the memory controller using a second setting;
- and
- send the first sampling results and the second sampling results to the memory controller;
- wherein
- the memory controller and/or the memory array are/is configured to adjust a setting for communicating or processing subsequent signals according to the first sampling results and the second sampling results.
