Claim 18:
19. A non-transitory computer-readable medium storing computer-readable instructions, such that when executed, causes a controller in a Solid State Drive (SSD) to manage storage of data in the SSD, including causing the controller to:
generate a plurality of payloads each containing data to be written to a NAND package and an identification (ID), the ID indicating one of a plurality of parallel mode interfaces corresponding to each of the plurality of payloads, wherein each of the plurality of parallel mode interfaces respectively corresponds to an individual one of a plurality of dies in the NAND package in the SSD, wherein the ID contained in the each of the payloads generated by the controller thereby specifies a respective individual one of the plurality of dies as a destination for the each payload; and
transmit the plurality of payloads via a serial link in the SSD to the NAND package, wherein:
the plurality of dies are grouped into a plurality of subsets; and
the NAND package comprises a second controller operatively and separately coupled in parallel to each of the plurality of subsets via a corresponding one of a plurality of parallel mode channels, each of the plurality of parallel mode interfaces corresponds to one of the plurality of parallel mode channels; and
wherein the second controller identifies, for the each payload, using the ID in the each payload generated by the controller, the corresponding one of the plurality of parallel mode channels from among the coupled plurality of parallel mode channels, and transmits the data in the each payload to the respective individual one of the plurality dies via the identified one of the plurality of parallel mode channels independently from the other of the plurality of parallel mode channels.
