I need help with following qeustions

Consider a 1Gbyte memory chip that does not use banks or rows/cols. If that chip has 8 data pins

How many address pins must it have? 30

How many pins for clock and ground? 2

How many control pins? 3

How many data pins? 8

How many total pins? 43

Let’s say we broken it up into 8 banks? How many total pins now? 43

Then why use banks? Concurrent reads
Let’s say we divided it into an even number of rows and columns. How many total pins now (but no banks)? 30

How do you get 30 for the last part of the question

please help thanks

Explanation / Answer

Memory chips are organized into a number of locations within the 1C. Each location can hold 1bit, 4 bits, 8 bits or even 16 bits depending on how it is designed internally. The number of bits that each location within the memory chip can hold is always equal to the number of data pins on the chip. The number of locations within a memory 1C always equals 2 to the power of the number of address pins.

230 = 1Gbyt (Approx)

Hence the answer is 30.
