Question

A PLA is similar to a ROM in concept except that ____________ *
2 points
It doesn’t provide full decoding to the variables
It hasn’t capability to read only
It hasn’t capability to read and write
None​

Answer 1

Answer: d

Explanation: The inputs in the PLD is given through AND gate followed by inverting & non-inverting buffer. PLDs are Programmable Logic Devices consisting of logic gates, flip-flops and registers connected together on a single chip. Thus, it can be categorised into PROM, PAL and PLA.

Answer 2

Answer: - (A) It doesn't provide full decoding to the variables.

Detailed answer: -

A PLA is similar to a ROM in concept except that it does not provide full decoding to the variables.

It also does not generate all the minterms as generated in the ROM.

About PLA: -

• PLA full form is Programmable Logical Array.
• PLA is a fixed architecture logic device which has programmable AND gates which are followed by programmable OR gates.
• It is basically a type of programmable logic, which is used to build a re-configurable digital circuit.
• They have an undefined function in it at the time of manufacturing, but they are then programmed before they are given or are used.

About ROM: -

• The full form of ROM is Read Only Memory.
• ROM is a type of a computer storage device.
• It consists of non-volatile permanent data that can only be read and not written or modified.
• ROM contains the programming which allows a computer to regenerate whenever we turn on a computer.
• It is useful for storing software in it.
• It is also used with other electronic devices to store data.
