Dynamic random access memory system switching between operation request types based on scoring and method for operating the same

An operating method of a dynamic random access memory system comprising:

• storing, when processing a plurality of first operation requests for dynamic random access memory media including a plurality of banks, the plurality of first operation requests in storage units corresponding to each of the plurality of banks respectively;
• classifying the plurality of first operation requests stored in the storage units into a plurality of types based on a reference first operation request;
• determining a score based on the number of first operation requests corresponding to each of the plurality of types;
• determining whether a switch condition is satisfied based on the score;
• and
• when the switch condition is satisfied, suspending processing of the plurality of first operation requests and changing to processing of a plurality of second operation requests for the dynamic random access memory media.
