Abstract
A memory module is operable to communicate data with a memory controller via a memory bus in response to memory commands received from the memory controller. The memory module comprises a plurality of memory integrated circuits arranged in ranks and including at least one first memory integrated circuit in a first rank and at least one second memory integrated circuit in a second rank, and further comprises a buffer coupled between the at least one first memory integrated circuit and the memory bus and between the at least one second memory integrated circuit and the memory bus. The memory module further comprises logic providing first control signals to the buffer to enable communication of a first data burst between the memory controller and the at least one first memory integrated circuit through the buffer in response to a first memory command, and providing second control signals to the buffer to enable communication of a second data burst between the at least one second memory integrated circuit and the memory bus through the buffer in response to a second memory command.
