Apparatus and method for generating descriptors to transfer data to and from non-volatile semiconductor memory of a storage drive

摘要

A storage drive including first, second, third, fourth and fifth modules. The first module is configured to control transfer of blocks of data between a host device and the storage drive. The second module is configured to transfer the blocks of data to and from a non-volatile semiconductor memory in the storage drive. The third module is configured to generate a first descriptor, which describes a transfer of blocks of data between the second module and the non-volatile semiconductor memory. The fourth module is configured to, according to the first descriptor, generate second descriptors. Each of the second descriptors corresponds to a respective one of the blocks of data. The fifth module is configured to generate instruction signals based on the second descriptors. The second module is configured to, based on the instruction signals, transfer the blocks of data between the first module and the non-volatile semiconductor memory.
