Design a 16K x 8 memory using the following ICs:

a. 1024 x1

b. 2K x4

c. 1Kx 8

Each IC has on-chip decoding, tristate outputs, and an enable pin.

d. Arrange the 16 chips needed in the design of problem (b) as a 4x 4 array and design the decoding circuitry.

Required memory size is 16k x 8

16k = 24 x 210 = 214

Hence, No. of address lines = 14

No. of data lines = 8

a) Size of IC 1024 x 1

Total number of ICs required = 16k x 8 / 1024 x 1 = 16 x 8 = 128

b) Size of IC 2k x 4

Total number of ICs required = 16k x 8 / 2k x 4 = 8 x 2 = 16

c) Size of IC 1k x 8

Total number of ICs required = 16k x 8 / 1k x 8 = 16 x 1 = 16

Explanation:

For a, 10 address lines from A0 to A9 are used to select any one of the memory location out of 1024 memory locations present in a IC.

For b, 11 address lines from A0 to A10 are used to select any one of the memory location out of 2k=2048 memory locations present in a IC.

For c, 10 address lines from A0 to A9 are used to select any one of the memory location out of 1k=1024 memory locations present in a IC.

explanation:

d. long term memory

the answer to your question would be something called hertz. the unit of measurement called a hertz, which is one cycle per second, is used to measure clock speed. within one cycle, your computer processes, refreshes, or updates itself to the changes that it is going through. in the case of computer clock speed, one hertz equals one tick per second. the clock speed of computers is usually measured in megahertz (mhz) or gigahertz (ghz)
