Abstract
A memory access circuit includes a write data circuit and a first write switch circuit. The write data circuit is used for receiving double data rate data or single data rate data, and outputting odd term data and even term data of adjusted double data rate data or adjusted single data rate data. The first write switch circuit is used for outputting the odd term data of the adjusted double data rate data to an odd block of a memory and outputting the even term data of the adjusted double data rate data to an even block of the memory when the write data circuit receives the double data rate data, and outputting the adjusted single data rate data to the even block or the odd block of the memory when the write data circuit receives the single data rate data.
