Abstract:
A memory controller may be configured with command logic that is capable of sending a memory access command having incomplete address information via a command/address bus that connects the memory controller to memory modules. The memory controller may send the memory access command via the bus for accessing data stored at memory locations of the memory modules. The memory locations may correspond to different near-memory generated reflecting that the data is not address aligned across the memory modules. Nonetheless, because of the near-memory address generation, the memory controller can send the memory access command having incomplete address information for accessing the data stored at the different addresses, as opposed to having to send multiple memory access commands specifying complete address information on the bus for accessing the data at the different addresses, thereby conserving usage of the available bus bandwidth, reducing power consumption, and increasing compute throughput.
