Abstract
PURPOSE: To enable to constitute the memory system incorporating the buffer memory in one chip, by setting the column address to the column address register at present address and performing access.
CONSTITUTION: The system provides the memory cell 2 of m x n bits, row address register 3 accessing the cell 2, and the data latch 5 corresponding to the row accessed based on the content of the register 3. After the content of the register 3 is set to the memory unit, the content of the column address register 4 is set, and the row address related to the address information accessed and the present row address related to the address information to be addressed are compared at the comparator. Further, when coincidence output is made, by setting only the column address to the register 4 at present access and performing access, through the use of existing memory unit, the memory system incorporating the buffer memory in one chip can be constituted.
