Buffer for testing a memory module and method thereof

摘要

In a method, a test pattern and an associated input mode may be received where the input mode may indicate a manner of applying the test pattern. An output test pattern is applied to at least one of a plurality of memory interface pins in accordance with the input mode. In a buffer, a test register may be configured to receive and store a test pattern and an associated input mode where the input mode may indicate a manner of applying the test pattern. The buffer may further include a test pattern generator configured to repeatedly generate an output test pattern based on the associated input mode.
