Which of the following statements are true? Check all that apply.
1.In a Read/Write memory, bit-lines transmit the information to be stored in memory cells, while word-lines transmit the Read/Write command.
2.A 220 x 16 words memory has a 16-bit data bus and a 220-bit address bus.
3.A 220 x 16 words memory requires a 20-to-220 address decoder
4.DRAM basic cell has fewer transistors than the SRAM one and therefore, DRAM memories may have a larger storage capacity than the SRAM memories.
5.DRAM memories retain information even when no power is supplied because they incorporate circuitry that periodically refreshes the information.
6.OTP ROM can be programmed up to 128 times.

 

Welcome to AAC.

This topic is here to help with homework, not to take exams for you.

If you need help with this question, you will have to show what work you have done to solve it, and people will give you advice on how to proceed to work it out on your own.

You won’t get help with this post as it stands.

 

the question 1 may be misleading because the bit-lines and the word lines lack the context to which single or multi mode registers they apply
-- it is the same to ask if the gears in car's rear differential have to do with one or another gear(-box gear)-change/-shift
otherwise https://slideplayer.com/slide/10500194/

the Q 5. is misleading also -- because there may be advanced chips to what is described under the https://en.wikipedia.org/wiki/Memory_refresh#Refresh_interval section

 

the Q 5. is misleading also --

I think the phrase “when no power is supplied “ makes it unambiguous.
