Test: Introduction to Memory Devices - Question 1

The full form of ROM is __________

Detailed Solution for Test: Introduction to Memory Devices - Question 1

The full form of ROM is Read Only Memory.

Test: Introduction to Memory Devices - Question 2

For reprogrammability, PLDs use __________

Detailed Solution for Test: Introduction to Memory Devices - Question 2

For reprogrammability, PLDs use EPROM (i.e. Erasable PROM). It erases the previous program and starts uploading a new one. However, data is erased by exposing it to UV-light, which is a tedious and time-consuming process.

Detailed Solution for Test: Introduction to Memory Devices - Question 3

The full form of EPROM is Erasable Programmable Read Only Memory, where the ROM can be erased and re-used by the user.
 

Test: Introduction to Memory Devices - Question 4

When both the AND and OR are programmable, such PLDs are known as __________

Detailed Solution for Test: Introduction to Memory Devices - Question 4

When both the AND and OR are programmable, such PLDs are known as PLA (i.e. Programmable Logic Array). However, PLA is more flexible but has less speed.

Test: Introduction to Memory Devices - Question 5

The programmability and high density of PLDs make them useful in the design of __________

Detailed Solution for Test: Introduction to Memory Devices - Question 5

The programmability and high density of PLDs make them useful in the design of ASIC (i.e. Application Specific Integrated Circuits) where design changes can be more rapidly and inexpensively.

Test: Introduction to Memory Devices - Question 6

The difference between FPGA and PLD is that __________

Detailed Solution for Test: Introduction to Memory Devices - Question 6

The difference between FPGA and PLD is that FPGA incorporates logic blocks instead of fixed AND-OR gates and is faster with low power dissipation. FPGAs are designed for having higher gate count whereas, PLDs are used for lesser gate counts.

Test: Introduction to Memory Devices - Question 7

ROM consist of __________

Detailed Solution for Test: Introduction to Memory Devices - Question 7

ROM consists of NAND and OR arrays which can be programmed by the user to implement combinational & sequential functions. Combinational Operations like that of adders and subtractors and Sequential Functions like that of storing in the memory.

Test: Introduction to Memory Devices - Question 8

The full form of PROM is __________

Detailed Solution for Test: Introduction to Memory Devices - Question 8

The full form of PROM is Programmable Read Only Memory, where the ROM can be programmed by the user.

Test: Introduction to Memory Devices - Question 9

PLDs with programmable AND and fixed OR arrays are called __________

Detailed Solution for Test: Introduction to Memory Devices - Question 9

PLDs with programmable AND and fixed OR arrays are called PAL (i.e. Programmable Array Logic). However, PAL is less flexible but has higher speed.

Test: Introduction to Memory Devices - Question 10

ASIC stands for __________

Detailed Solution for Test: Introduction to Memory Devices - Question 10

In digital electronics, ASIC stands for Application Specific Integrated Circuits. It is a customized integrated circuit which is produced for a specific use and not for a common-purpose.
