Data processing methods for memory devices, controllers, and computer systems

Abstract

The invention relates to a method for processing data for memory devices, controllers, and computer systems, and relates to the field of data storage technology, such that memory capacity expansion can be performed, and memory capacity expansion is not limited by the original number of double data rate (DDR) channels. The memory device comprises a controller, primary memory, and secondary memory, the controller communicating separately with the processor, primary memory, and secondary memory. And the read / write performance of the first memory is higher than the read / write performance of the second memory. This method includes the steps of: receiving a processor operation request, which includes a logical address; and accessing the first or second memory based on the logical address.
