Question 1

How many address bits would be required for a memory that stores 64, 4- bit words?

Accepted Answer

A

Question 2

Which of the following are the four basic parts of ROM architecture?

Accepted Answer

The four basic parts of ROM architecture are the row decoder, column decoder, register array, and output buffer. These components work together to store data, decode addresses, and output data.

Question 3

Which of the following is an advantage that an EEPROM has over an EPROM?

Accepted Answer

EEPROMs can be erased and reprogrammed without removal from the circuit, and they have the ability to erase and reprogram individual words, offering more flexibility compared to EPROMs.

Question 4

Capacity, when used to define memory devices, normally refers to the number of:

Accepted Answer

Memory capacity is typically measured in bits, as it represents the smallest unit of data in computing.

Question 5

A computer's internal memory consists of:

Accepted Answer

The answer of A computer's internal memory consists of:
...

Question 6

How many address lines would be required for a 4 K × 4 memory?

Accepted Answer

A 4K memory requires 12 address lines because 4K is 2^12, and each address line represents a binary digit.

Question 7

Which of the following are normally used to initialize a computer system's hardware?

Accepted Answer

Bootstrap memory is used to initialize a computer system's hardware. It contains the initial program that the computer runs when it is powered on or reset, often referred to as the bootloader or firmware, which starts the process of loading the operating system.

Question 8

Which of the following terms best describes Read- Only- Memory (ROM)?

Accepted Answer

ROM is nonvolatile, meaning it retains its data without power, and is used to store information that does not change during system operation, such as firmware.

Question 9

Of the following memory devices, which two would store the same number of bits?
 1. 1024 K × 8
2.1M*10
3.2M*4
4.1M*4

Accepted Answer

1. 1024 K × 8 = 1024 * 1024 * 8 bits (since 1K = 1024 and K = 1024)2. 2M * 4 = 2 * 1024 * 1024 * 4 bits (since 1M = 1024 * 1024)Both 1 and 3 result in 8,388,608 bits.

Question 10

A major disadvantage of the Mask- Programmed ROM (MROM) is that it:

Accepted Answer

Mask-Programmed ROM (MROM) is manufactured with data permanently written during the fabrication process, making it impossible to reprogram or change the stored data after production.

Question 11

How many bits of information could normally be stored in a memory device with a capacity of 256 K?

Accepted Answer

A kilobyte (K) is conventionally considered as 1024 bytes, not 1000. Therefore, 256 Kbytes equals 256 * 1024 bytes. Since each byte contains 8 bits, the total number of bits is 256 * 1024 * 8 = 262,144 bits.

Question 12

Suppose that a computer system has a read/write line identified as . When writing to memory:

Accepted Answer

The answer of Suppose that a computer system has a...

Question 13

Most ROM ICs have tri- state outputs that:

Accepted Answer

Tri-state outputs on ROM ICs allow for the connection of multiple ROM chips to a common data bus by enabling an output, disabling it to a high-impedance state, or maintaining a normal logic level, thus facilitating the sharing of the bus without interference.

Question 14

Which of the following is used to erase an EPROM?

Accepted Answer

EPROM (Erasable Programmable Read-Only Memory) can be erased and reprogrammed by exposing it to strong ultraviolet light. The UV light causes the charge stored in the floating gate of each cell to dissipate, effectively erasing the memory so that it can be rewritten.

Question 15

Which of the following best describes Random Access Memory (RAM)?

Accepted Answer

Random Access Memory (RAM) is characterized by the ability to access any memory location directly and in the same amount of time, regardless of where the memory location is.

Question 16

How many bytes can be stored in an 8K × 8 memory chip?

Accepted Answer

An 8K × 8 memory chip means it has 8K (K = 1024) locations, each storing 8 bits (1 byte). Therefore, it can store 8 * 1024 = 8192 bytes.

Question 17

How many data outputs are required for a 64 × 8 memory chip?

Accepted Answer

A 64 × 8 memory chip means it has 64 memory locations, each storing 8 bits. Therefore, it requires 8 data outputs to output the data stored in any one of the 64 locations.

Question 18

The delay between the application of an address to a ROM and the appearance of valid data at its outputs is called:

Accepted Answer

Access time, denoted as t_acc, is the correct term for the delay between applying an address to a ROM and when valid data appears at its outputs.

Question 19

Data that is stored in ROM is often referred to as:

Accepted Answer

Firmware is the term used to describe the data stored in ROM (Read-Only Memory). It refers to the permanent software programmed into a read-only memory.

Question 20

Which of the following best describes volatile memory?

Accepted Answer

Volatile memory loses its stored information when the electrical power is turned off or interrupted. This is in contrast to non-volatile memory, which retains data even when power is removed. Examples of volatile memory include RAM (Random Access Memory) used in computers and other devices.
