How to calculate memory size ?|| How to calculate number of bits in Address

#MemorySize #AddressBus #Howtocalculatememorysize #Howtocalculateaddressbuswidth This video explains the the how one can calculate the memory size using the address bus and how one can calculate the address bus width using the memory size. the size of memory is really important term and one needs to know especially programming in assembly language.

Can you please tell how can we represent 65bits in ram size?

[@LearnOnline1]

Your question is not clear. However, If I understand correctly. you mean 65 bits in the address. then you will have 2^65 locations and let say each location can carry m bits then the capacity of ram will be 2^65 *m.

@@LearnOnline1 if the ram size is 22mb so the address width bit is 25?

[@LearnOnline1]

@@shahrozatiq5312 22 MB seems something awkward. it should be the power of 2. For example, could be 2,4,8,16 something like that. for 25-bit address... 2^25=2^20* 2^5=1M *32 =32M locations. Assuming each location is 1B so 32MB Capacity.

@@LearnOnline1 today was my test and question was If the ram size is 26mb ,_______ would be the number of bits.
So I write 25 cause 26mb will fall in 2^5 x 2^20

[@LearnOnline1]

@@shahrozatiq5312 your question is not complete. ...... WOULD BE NUMBER OF BITS IN WHAT ?? in address ? or in RAM? For example, in RAM it would be= 26MB=26*2^20*8 bits in terms of Capacity shown in bits. However, if the question is about a number of bits in the Address then my previous solution is valid.

nice work

Thanks

What about 6kb ??

[@LearnOnline1]

Assuming 8bits are stored in one location as asssumed in the same video..one cant completely break down it into power of 2. So either of is done with cascading of two or more smaller campacity chips. Or one can use bigger chip like 8KB. And some of the addres range is not used for real addressing .
