Abstract
A method of managing memory descriptors for a plurality of commands to a non-volatile semiconductor storage device includes requesting memory descriptors from a host system for each of the plurality of commands stored in a first memory, storing the memory descriptors for each of the plurality of commands in free descriptor regions of a plurality of descriptor regions in a second memory of the non-volatile semiconductor storage device, and maintaining a dynamic descriptor list in the second memory for each of the plurality of commands, the dynamic descriptor list for each of the plurality of commands comprising occupied descriptor regions of the plurality of descriptor regions in the second memory having associated memory descriptors. At least one of the occupied descriptor regions includes multiple memory descriptors and a single pointer to a next occupied descriptor region of the plurality of descriptor regions.
