For an efficient memory use, a memory control method of the present invention of a character multiplexed broadcast receiver for controlling utilization of a data storing field (1) provided for storing data of pages of programs emitted in a character multiplexed broadcast comprises a step of checking when data of a page of a program are received whether the same data of the same page of the same program are already stored or not in any of blocks (1-1 to 1-n) of the data storing field (1) by searching an information table (3) comprising lines (3-1 to 3-l) sorted where is registered information of data stored in one of the blocks (1-1 to 1-n); a step of storing the data in an available block found by retrieving a status bit table (2) comprising a basic bit sequence (2-0), logic of its each bit indicating status of each corresponding block (1-1 to 1-n; a step of registering information of the data in the information table (3) by adding a new line; and a step of sorting the information table.
