<p>A synchronous dynamic random access memory controller is disclosed, and which is configured to: after receiving a writing operation request from a user, choose one or more mirror spaces used for backing up writing operation data, and said mirror spaces are the address spaces that locate in the synchronous dynamic random access memory in the different memory arrays from the writing address of the writing operation request, and process a plurality of reading operation requests in parallel, and the mirror spaces selected for various reading operation requests for reading data are located in different arrays in the synchronous dynamic random access memory. Said synchronous dynamic random access memory controller includes an operation generator module and a mirror operation process module connected with each other. A method and an apparatus for reading data with the synchronous dynamic random access memory controller are also disclosed. The present invention can increase the speed of processing the reading operation requests from a user with the synchronous dynamic random access memory controller, and reduce the delayed processing time of the reading operation request.</p> |
