Abstract: A memory controller and buffers on memory modules each operate in two modes, depending on the type of motherboard through which the controller and modules are connected. In a first mode, the controller transmits decoded chip-select signals independently to each module, and the motherboard data channel uses multi-drop connections to each module. In a second mode, the motherboard has point-to-point data channel and command address connections to each of the memory modules, and the controller transmits a fully encoded chip-select signal group to each module. The buffers operate modally to correctly select ranks or partial ranks of memory devices on one or more modules for each transaction, depending on the mode.

Abstract: In an embodiment, a processor comprises a reservation station that issues a first load operation for execution, a store queue, and a replayed load buffer coupled in parallel with the reservation station. During execution of the first load operation, the store queue detects that the first load operation hits on a first store operation in the store queue that lacks store data and causes a replay of the first load operation. The replayed load buffer captures an identifier of the first load operation and the first store operation based on the replay of the first load operation, wherein the replayed load buffer monitors the reservation station for issuance of a first store data operation corresponding to the first store operation and issues the first load operation for reexecution based on the issuance of the first store data operation.
