Hybrid Non-Volatile Memory System |
摘要 |
A hybrid non-volatile system uses non-volatile memories based on two or more different non-volatile memory technologies in order to exploit their relative advantages. In an exemplary embodiment, the memory system includes a controller and a flash memory, where the controller has a non-volatile RAM based on an alternate technology such as FeRAM. The flash memory is used for the storage of user data and the non-volatile RAM in the controller is used for system control data. The use of an alternate non-volatile memory technology in the controller allows for a non-volatile copy of the most recent control data to be accessed more quickly as it can be updated on a bit by bit basis. In another exemplary embodiment, the alternate non-volatile memory is used as a cache where data can safely be staged prior to its being written to the memory or read back to the host.
