MEMORY DEVICE AND METHOD FOR DATA EXCHANGING THEREOF

摘要

The application discloses a memory device. The memory device has a volatile memory module and a non-volatile memory module. The memory device receives a data access command from an external module through a memory interface and exchanges data with the external module accordingly. An access control module is coupled to the memory interface to receive the data access command. A non-volatile memory controller is coupled to the non-volatile memory module. The non-volatile memory module receives the data access command and exchanges data with the non-volatile memory module accordingly. A data buffering module is coupled to the volatile memory module, the non-volatile memory controller and the memory interface. The data buffering module is also coupled to the access controller module to receive the data access command. The data buffering module provides the data access command to the non-volatile memory controller to exchange data with the non-volatile memory controller according to the data access command. The data buffering module has a buffer memory for storing at least a portion of data exchanged through the data buffering module.
