Claim 15:
16. A method of managing storage of data in a solid state drive (SSD), the method comprising:
generating, by a first controller in the SSD, a plurality of payloads, each of the payloads containing data to be written to a NAND package and an identification (ID), the ID indicating one of a plurality of parallel mode interfaces in the SSD 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 payload generated by the first controller thereby specifies a respective individual one of the plurality of dies as a destination for the each payload; and
transmitting, by the first controller, 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;
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
the second controller identifies, for the each payload, using the ID in the each payload generated by the first 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 of dies via the identified one of the plurality of parallel mode channels independently from the other of the plurality of parallel mode channels.
