Question

Match the following:

(a) Field Programmable	(i) Referring to a PROM that can be programmed only by the manufacture.
(b) Mask Programmable	(ii) Referring to the content addressable memory
(c) Associative	(iii) Non-volatile memory that can be written and erased electrically
(d) Flash	(iv) referring to a PROM that can be programmed by the user

1. (a)-(iv), (b)-(i), (c)-(2), (d)-(iii)
2. (a)-(i), (b)-(iv), (c)-(2), (d)-(iii)
3. (a)-(iii), (b)-(i), (c)-(ii), (d)-(iv)
4. (a)-(ii), (b)-(i), (c)-(iv), (d)-(iii)

Answer 1

Correct Answer - Option 1 : (a)-(iv), (b)-(i), (c)-(2), (d)-(iii)

Field programmable:

• FPGA (Field Programmable Gate Array) is an Integrated Circuit which can be reconfigured again and again to perform different tasks as desired.
• Field programmable implies that FPGAs can be programmed at home, at the office or anywhere outside of the IC fabrication factory.
• So, Field Programmable is referring to a PROM that can be programmed by the user.

Mask programmable:

• In the case of Mask-programmed ROM, the ROM is programmed at the manufacturer's side according to the specifications of the customer, i.e. information is stored at the time of its manufacturing.
• It cannot be altered or erased later on.

Associative:

• An associative memory can be considered as a memory unit whose stored data can be identified for access of the content, i.e. associative memory is accessed by the content of the data rather than by the address.
• It is also called as Content Addressable Memory (CAM)

Flash:

• It is a non-volatile memory chip used for storage and for transferring data between a personal computer (PC) and digital devices.
• It is electronically erasable, electronically programmable read-only memory.
• It offers faster read access times and better kinetic shock resistance than the hard disks.
