The memory content may be cached in the non-volatile cache when a computing system is entering Sstate. The non-volatile cache may be coupled to a bus that connects the disk drive with the disk controller. When resuming from Sstate, the memory content may be read from the non-volatile cache rather than from the slow disk drive, which facilitates instant-on resuming for the system. The caching process may be performed in an OS-transparent manner. During the caching process, data with contiguous addresses may be merged into a block of data. A mapping table may be created and stored in the non-volatile cache which includes multiple entries, each for a block of data. The mapping table facilitates data reading from the non-volatile cache to provide instant-on resuming from Sstate.
