Mapping memory controller connectors to memory connectors

摘要

Provided are a device, system, and method for mapping memory controller connectors to memory connectors. A memory is programmed to transmit for each of a plurality of the memory data connectors, a pattern on the memory data connectors that has a first value for a selected memory data connector of the memory data connectors and a different value from the first value for the memory data connectors other than the selected memory data connector. For each of the memory data connectors, a read command is issued to read the pattern on the memory data connectors. a device data connector receiving the first value in the read pattern is mapped to the selected memory data connector transmitting the first value.

1. A device comprising:
device data connectors that connect to a memory channel connecting to memory data connectors on a memory; logic that when executed is to:
program the memory to indicate a pattern specifying a value to output for each of the memory data connectors;for each of the memory data connectors comprising a selected memory data connector of the memory data connectors, perform:
program the memory to mask the selected memory data connector, wherein the program the memory to mask the selected memory data connector is to cause the selected memory data connector to output a mask value different from the value specified by the pattern;issue a read command to read the pattern of the values on the memory data connectors; andmap a device data connector of the device data connectors receiving the mask value in the read pattern to the selected memory data connector transmitting the mask value.
