Memory system including variable write burst and broadcast command scheduling

摘要

A system includes a host device that may be configured to initiate memory requests to a system memory. The system also includes a memory controller that may be configured receive the memory requests and to format the memory requests into memory transactions that are conveyed to the memory device via a memory interface. The memory transactions include a memory write burst command having a first frame that includes a corresponding opcode positioned in one of a first command slot or a second command slot. The memory write burst command may also include a number of subsequent frames for conveying a data payload, as specified for example, by the opcode. The control unit may be configured to generate a number of concurrent sequential memory write operations to the memory in response to receiving the memory write burst command.

1. A memory subsystem, comprising:
a memory device comprising a plurality of independently accessible memory partitions; and a control unit coupled to the memory device and configured to read and write data to the memory device in response to receiving memory transactions via a memory interface; wherein the control unit is configured to perform memory transactions that include a memory write burst command having a first frame that specifies a starting address in the memory device, and further having a plurality of subsequent frames for conveying a data payload; and wherein the control unit is configured to generate a number of memory write operations to the memory in response to receiving the memory write burst command, wherein the memory write operations write the data payload from each subsequent frame to a different memory partition, beginning with a partition specified in the memory write burst command, wherein the data payload is written to the different memory partitions at the starting address.
