This set of Computer Organization and Architecture Multiple Choice Questions & Answers (MCQs) focuses on “Large Memories”.
1. The chip can be disabled or cut off from an external connection using ______
a) Chip select
b) LOCK
c) ACPT
d) RESET
View Answer
Explanation: The chip gets enabled if the CS is set otherwise the chip gets disabled.
2. To organise large memory chips we make use of ______
a) Integrated chips
b) Upgraded hardware
c) Memory modules
d) None of the mentioned
View Answer
Explanation: The cell blocks are arranged and put in a memory module.
3. The less space consideration as lead to the development of ________ (for large memories).
a) SIMM’s
b) DIMS’s
c) SRAM’s
d) Both SIMM’s and DIMS’s
View Answer
Explanation: The SIMM (single inline memory module) or DIMM (dual inline memory module) occupy less space while providing greater memory space.
4. The SRAM’s are basically used as ______
a) Registers
b) Caches
c) TLB
d) Buffer
View Answer
Explanation: The SRAM’s are used as caches as their operation speed is very high.
5. The higher order bits of the address are used to _____
a) Specify the row address
b) Specify the column address
c) Input the CS
d) None of the mentioned
View Answer
Explanation: None.
6. The address lines multiplexing is done using ______
a) MMU
b) Memory controller unit
c) Page table
d) Overlay generator
View Answer
Explanation: This unit multiplexes the various address lines to lesser pins on the chip.
7. The controller multiplexes the addresses after getting the _____ signal.
a) INTR
b) ACK
c) RESET
d) Request
View Answer
Explanation: The controller gets the request from the device needing the memory read or write operation and then it multiplexes the address.
8. The RAS and CAS signals are provided by the ______
a) Mode register
b) CS
c) Memory controller
d) None of the mentioned
View Answer
Explanation: The multiplexed signal of the controller is split into RAS and CAS.
9. Consider a memory organised into 8K rows, and that it takes 4 cycles to complete a read operation. Then the refresh overhead of the chip is ______
a) 0.0021
b) 0.0038
c) 0.0064
d) 0.0128
View Answer
Explanation: The refresh overhead is calculated by taking into account the total time for refreshing and the interval of each refresh.
10. When DRAM’s are used to build a complex large memory, then the controller only provides the refresh counter.
a) True
b) False
View Answer
Explanation: None.
