Abstract
A DRAM memory includes: a substrate; a plurality of memory banks arranged in rows and columns on the substrate, each memory bank is divided into three memory blocks in the column direction. Each memory block has a number of memory cells arranged in rows and columns. Dividing each memory bank into three memory blocks in the column direction shortens the length of the memory bank in the row direction, as each memory bank has a certain capacity, so a large drive is no longer required. In addition, the distance from the control circuit and the data transmission circuit to the corresponding memory cell in the memory array in each memory bank will be shorter too, reducing parasitic resistance and parasitic capacitance generated from the data transmission circuit. As a result, the data transmission rate and data transmission accuracy are improved. The overall power consumption is reduced.
