EARLY DE-ALLOCATION OF WRITE BUFFER IN AN SSD |
摘要 |
A data storage system includes: non-volatile solid state memory including non-volatile storage units and a temporary register; a data storage controller configured to receive a write command including a plurality of logical segments of data from a host; a write buffer allocated to receive a portion of the plurality of logical segments of data and accumulate a physical segment of data corresponding to a write unit of the solid state memory; a solid state memory controller configured to transmit the accumulated data from the write buffer to the temporary storage register each time the write buffer accumulates a physical segment of data. The data storage controller acknowledges completion of the write command to the host after the last logical segment of data is written to the write buffer; and deallocates the write buffer after the solid state memory completes reception of the accumulated data into the temporary storage register. |
