SYSTEM AND METHOD OF INTERLEAVING DATA RETRIEVED FROM FIRST AND SECOND BUFFERS

摘要

A host interface communicates with a non-volatile memory (NVM) device over a bus. The host interface includes a first buffer, a second buffer and a scatter/gather list (SGL). The first buffer stores blocks of application data to be communicated to the storage device. The second buffer stores blocks of protection data added by the host interface with respect to the blocks of application data stored in the first buffer. The SGL utilizes a first descriptor type that includes a first buffer address, a first buffer interleave burst length, and a burst count, and a second descriptor type that includes a second buffer address, and a second buffer interleave burst length, wherein only a first descriptor and a second descriptor is required to interleave application data from the first buffer with protection data from the second buffer.

1. A host system that communicates with a non-volatile memory (NVM) device over a network, the host system comprising:
a first buffer that stores blocks of application data to be communicated to the NVM device; a second buffer that stores blocks of protection data added by the host interface with respect to the blocks of application data stored in the first buffer; and a scatter/gather list (SGL) that utilizes a first descriptor type that includes a first buffer address, a first buffer interleave burst length, and a burst count, and a second descriptor type that includes a second buffer address, and a second buffer interleave burst length, wherein only a first descriptor and a second descriptor is required to interleave application data retrieved from the first buffer with protection data retrieved from the second buffer.
