Abstract
The invention is related to a method, a computer program product and an apparatus for scheduling and executing host data-update commands. The method, performed by a processing unit, includes: generating third host data-update command and labeling the third host data-update command as a first-type of host data-update command according to a type and parameters of a host command for updating data from a host-side; deleting the redundant first logical address from the matched first host data-update command in response to a third logical address of the third host data-update command being equal to a first logical address in one of first host data-update commands in the first queue; deleting the redundant second logical address from the matched second host data-update command in response to the third logical address of the third host data-update command being equal to a second logical address in one of second host data-update commands in the second queue; and pushing the third host data-update command into the first queue. With the aforementioned method, errors of dirty write would be avoided.
