A data processing system comprises a storage device, an interface module and a scheduler. The interface module is configured to dispatch a non-prioritized request via a first data path, and to transfer application-level information of an application via a second data path. The scheduler, coupled to the first and second data path, is configured to enable an access to the storage device according to the non-prioritized request and the application-level information respectively received from the first and second data paths.

Data processing method and system with application-level information awareness

A method for operating a memory includes receiving a command to program a data value at a memory cell, and an indication of which write mode in a plurality of write modes to use. Write modes in the plurality are characterized by different sets of resistance ranges that correspond to data values stored in the memory cell. The method includes executing a program operation according to the indicated one in the plurality of write modes to program the data value in the memory cell. The plurality of write modes includes a first write mode and a second write mode corresponding to shorter data retention than the first write mode. The first and second write modes are characterized by first and second sets of resistance ranges in the different sets of resistance ranges. The method includes periodically refreshing data values in memory cells storing data in the second write mode.
