In the following, let r be the number of rows in a DRAM array, c the number of columns, b_r the number of bits needed to address the rows, and b_c the number of bits needed to address the columns. For each of the following DRAMs, determine the power-of-2 array dimensions that minimize max(b_r, b_c), the maximum number of bits needed to address the rows or columns of the array.

Organization 16 x 1 16 x 4 128 x 8 512 x 4 1,024 x 4 b be max(b, b)
