摘要： In general, techniques are described for initializing a memory module in accordance with a programmable initialization sequence. A memory controller, for example, includes a programmable computer-readable medium that stores configuration data to control initialization of one or more memory modules. The memory controller includes an initialization control unit that outputs a sequence of commands to initialize the memory modules in accordance with the configuration data. The initialization control unit may select the sequence of commands from a set of predefined initialization sequences based on the configuration data.

摘要： A system and method for testing and/or initializing a Directory Store in a directory-based coherent memory. In one illustrative embodiment, the directory-based coherent memory includes a Main Store for storing a number of data entries, a Directory Store for storing the directory state for at least some of the data entries in the Main Store, and a next state block for determining a next directory state for a requested data entry in response to a memory request. To provide access to the Directory Store, and in one illustrative embodiment, a selector is provided for selecting either the next directory state value provided by the next state block or another predetermined value. The other predetermined value may be, for example, a fixed data pattern, a variable data pattern, a specified value, or any other value suitable for initializing and/or testing the Directory Store. The output of the selector may be written to the Directory Store.
