Method of accessing synchronous dynamic random access memory, memory control circuit, and memory system including the same |
摘要 |
An access area is set within an address space of a dynamic random access memory by arranging two or more complete columns of blocks, in which blocks of memory cells are arranged within an entirety of a specified range of row addresses, along a direction of column addresses. Each of the blocks includes memory cells positioned at a same row address and a specified number of consecutive column addresses. The total number of blocks arranged in the access area is just capable of storing the number of words of the data to be stored. The two or more complete columns of blocks are successively accessed by successively accessing the blocks arranged in each of the columns of blocks. Thereby, a refresh operation of the dynamic random access memory is made unnecessary.
