Suggest reasons why RAM traditionally have been organized as only one bit per chip where as ROM are usually organized with multiple bits per chip?

Answer 1

The 1-bit-per-chip organization has several advantages. It requires

fewer pins on the package (only one data out line); therefore, a higher

density of bits can be achieved for a given size package. Also, it is

somewhat more reliable because it has onoy one output driver. These

benefits have led to the traditional use of 1-bit-per-chip for RAM. In

most cases, ROMs are much smaller than RAMs and it is often possible to get

an entire ROM on one or two chips if a multiple-bits-per-chip organization

is used. This saves on cost and is sufficient reason to adopt that

organization.

Answer 3

Neither RAM nor ROM has been organized as one bit per chip, even in early versions of the chips. For instance, the original RAM chip featured 512 x 8 bits.
