A memory access method convolutes plural data using maximal-sequence codes having individual phase shifting quantities and writes the convoluted data into a cyclic memory (1, 12, 13, 14, 21). The memory access apparatus reads out a desired data from the cyclic memory (1, 12, 13, 14, 21) using corresponding maximal-sequence code. A memory access method convolutes plural data using sequence codes which is obtained weighting factoes and maximal-sequence codes having individual phase shifting quantities and writes the convoluted data into a cyclic memory (1, 12, 13, 14, 21).
