MEMORY INTERFACE AND ADAPTIVE DATA ACCESS METHOD

A data access method for an application circuit to access a memory. The method includes steps of: receiving a first data from the application circuit; duplicating the first data to obtain a duplicated first data; and writing the first data and the duplicated first data into the memory at continuously accessible addresses. For accessing to the first data, the first data and the duplicated first data are read from the memory in response to a rising edge and a falling edge of a data-triggering signal; and one of the first data and the duplicated first data is outputted while the other of the first data and the duplicated first data is discarded.
