Abstract
There is provided a data memory apparatus which can efficiently use a general-purpose DRAM as a memory used during the digital data error correcting and modifying processing. The apparatus is comprised of a DRAM, a DRAM access unit and an error correcting circuit. Input digital data is first subjected to the error correcting processing by means of the error correcting circuit, assigned with a result of the error correcting processing and transferred to the DRAM access unit. The DRAM access unit accesses the DRAM in a page mode to store the data in the DRAM.
