Abstract:
A memory controller has an interface to convey, over a first set of interconnect resources: a first command that specifies activation of a row of memory cells, a second command that specifies a write operation directed to the row of memory cells, a bit that specifies whether precharging will occur in connection with the write operation, a code that specifies whether data mask information will be issued in connection with the write operation, and if the code specifies that data mask information will be issued, data mask information that specifies whether to selectively write portions of write data associated with the write operation. The memory controller interface further conveys, over a second set of interconnect resources, separate from the first set of interconnect resource, the write data.
