Chip size is an important packaging parameter and contributes greatly to system size. It is largely determined by the number of pins. Assume a memory chip holding 1M bits, with non-multiplexed address and data. How many address and data pins are required when the chip is internally organized as 1Mb x 1 bit, 512 kb x 2 bits, 256 kb x 4 bits and 128kb x 8 bits?
