APPARATUS AND METHOD FOR GENERATING DESCRIPTORS TO TRANSFER DATA TO AND FROM NON-VOLATILE SEMICONDUCTOR MEMORY OF A STORAGE DRIVE

摘要

the first, second, third, fourth and fifth modules, including the storage drive is to be provided. Wherein the first module is configured to control the transfer of data blocks between the host device and the storage drive. Wherein the second module is configured to deliver the data block from the nonvolatile semiconductor memory and the nonvolatile semiconductor memory in the storage drive. Wherein the third module is configured to generate a first descriptor describing the transfer of data blocks between the second module and the non-volatile semiconductor memory. The fourth module is configured to generate a second descriptor in accordance with the first descriptor. Each of said first descriptor corresponds to each data block of the data block. The fifth module is configured to generate command signals based on the second descriptor. The second module is based upon the command signal, and forward of the first module and the non-volatile data blocks between the semiconductor memory. ;
