Memory and Cache Quiz

The Cache memory operates based on the principle:

• The operating principle of the computer

• The principle of data write control

• The principle of memory reference locality

• The principle of data read control

With an SRAM memory chip having n address lines and m data lines, the capacity of the chip is:

• 2m x n bytes

• 2n x m bytes

• 2m x n bits

• 2n x m bits

Considering the Cache memory, which of the following address mapping techniques is used?

• Direct, fully associative, set-associative

• Direct, continuous associative, interrupted associative

• Set-associative, element associative, combined associative

• Direct, indirect, combined

The main memory is usually made up of which of the following memory elements?

• EPROM

• EEPROM

• DRAM

• SRAM

Characteristics of RAM memory in general:

• Allows data reading only

• Allows data writing

• Does not lose data when power is off

• Allows simultaneous read/write at a memory location

What is the structure of a DRAM memory cell?

• Consists of two capacitors and two transistors

• Consists of two capacitors and two transistors

• Consists of two capacitors and one transistor

• Consists of one capacitor and one transistor

Regarding the method of writing data to the Cache, which of the following statements is incorrect?

• Write-through has a slow write speed because it writes simultaneously to both Cache and main memory

• Write-back has a slow write speed because it needs to check if the corresponding block in the Cache is replaced

• Write-back only writes to the Cache, and only writes back the entire block to main memory when the corresponding block in the Cache is replaced

• Write-through writes simultaneously to both Cache and main memory

Regarding RAM memory, which of the following statements is incorrect:

• It is a non-volatile memory

• It is a random access read/write memory

• There are two types of RAM: SRAM and DRAM

• It temporarily stores information when executing a program

Among modern computers, which memory device of the following types typically has the largest capacity?

• Hard disk

• RAM

• ROM

• Cache

Which of the following statements about PROM is correct?

• The manufacturer preloads the data, and the user cannot erase the data

• The user can erase the data using a UV light device and reload data electrically

• The user can load or erase data electrically

• Requires a specialized device to write data, and the user cannot erase the data
