CHAPTER 1

There are 30 other addresses that can select the other 30 words. ROM is sometimes specified by the total number of bits it contains, which is 2n X m. Ex: a 2048-bit ROM may be organized as 512 words of 4 bits each. It means that the unit has 9 input lines and 4 output lines to specify 29 = 512 words. ................
