Abstract
A memory module comprises a volatile memory subsystem including DRAM, a non-volatile memory subsystem including Flash memory, and a module control device. The Flash memory includes main Flash providing a main Flash memory space and scratch Flash providing a scratch Flash memory space. The module control device is configured to receive a request from the memory controller to move one or more segments of data in a first Flash block in the main Flash to the DRAM and to, for each respective segment of data: select a respective set of pages in the DRAM; transfer respective data stored in the respective set of pages from the DRAM to a corresponding segment in the scratch Flash; and transfer the respective segment of data to the respective set of pages in the DRAM. Thus, data can be moved segment by segment between the DRAM and the Flash memory.
