A memory controller receives a command to perform a memory operation, the command including a data packet comprising a plurality of data divisions. In response to receiving the command, for each individual memory device, the memory controller assigns to the individual memory device a respective data division, the respective data division including a plurality of data segments, and determines a single relative memory address associated with an address specified by the received command. The memory controller assembles a sub-request comprising a single contiguous instruction portion, which includes the single relative memory address and one or more instructions to perform the memory operation, and the respective data division, the respective data division following the single contiguous instruction portion, and transmits the sub-request to every memory portion of the number of memory portions of the individual memory device.

Multi-package segmented data transfer protocol for sending sub-request to multiple memory portions of solid-state drive using a single relative memory address

Locally generating and storing RAID stripe parity with single relative memory address for storing data segments and parity in multiple non-volatile memory portions

A first memory portion of a plurality of memory portions is configured to determine a designated position of the first memory portion (in a predefined sequence of the plurality of memory portions), and to receive a sub-request conveyed to the plurality of memory portions in the first memory device. The sub-request has a single contiguous instruction portion and a plurality of data segments. The single contiguous instruction portion has a single relative memory address and a single set of one or more instructions to write the data segments. The first memory portion detects that the received sub-request includes an instruction to write data, and in response, identifies a first data segment allocated to the first memory portion, places the first data segment into a buffer of the first memory portion, and writes the buffered first data segment to a location in non-volatile memory of the first memory portion.
