the 16 bit ram the 16 bit ram produces an output signal representative of the bit at the intersection of the selected row and column there are 16 such intersections and thus sixteen such bits there are 2 16 possible combinations of functions capable of being represented by the set of 16 bits present in the 16 bit ram thus if a nor gate is to be simulated by the 16 bits in the ram the karnaugh map for the ram would be as shown in fig3 c in fig3 c all bits are 34 0 34 except the bit at the intersection of the first row representing a 0 b 0 and the first column representing c 0 d 0 should a less frequently used function be desired to be generated by the 16 bit ram for example should a 34 1 34 output signal be desired for a 1 b 0 c 0 and d 0 then a binary 34 1 34 is stored at the intersection of the second row and the first column should a binary 34 1 34 be desired both when a 0 b 0 c 0 and d 0 and also when a 1 b 0 c 0 and d 0 then a binary 34 1 34 is stored at each of the intersections of the first column with the first row and the second row the logic circuit represented by this.
