Step 1 of 2 16.015P Consider a 1-Gbit dynamic RAM (DRAM) with a cell size of 0.38x0.76 µm² Calculate the cell area. The cell area = (RAM capacity)(cell size) Substitute 1 G-bit for RAM capacity, and 0.38x0.76 µm² for cell size. The cell area = =0.289 Consider that the chip size is, 19x38 The total chip area in is, The total chip area = =0.722 Step 2 of 2 The space occupied by I/O connections, peripheral circuits on the chip is, Total chip area - Total cell area = 0.722 - 0.289 =0.433 The percentage of space occupied by the peripherals in total chip area is, The fraction of chip area occupied by peripherals = 0.433 100 0.722 =60% Therefore, in total chip area 40% of space occupied by the cell area and remaining 60% space occupied by the I/O connections, peripheral circuits, and interconnect.
