DATA WRITE CONTROL APPARATUS AND METHOD

摘要

A data write control apparatus and method. The method comprises: when the write control apparatus is in a write-back mode, detecting, by a processor, the number of garbage blocks in a first memory unit; when the number of garbage blocks reaches a first preset threshold, respectively predicting an execution progress of a program run by the processor within a danger time period in two write modes; if the execution progress of the program run by the processor within a danger time period in a write-through mode is predicted to be greater than that in the write-back mode, switching a current data write mode to the write-through mode; when the write control apparatus is in the write-through mode, detecting the number of garbage blocks; when the number of garbage block decreases to a second preset threshold, switching a current data write mode to the write-back mode.
