Correct Answer - Option 1 :

Both Statement (I) and Statement (II) are individually true and Statement (II) is the correct explanation of Statement (I)


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)
  • It is a special type of computer memory used in certain very-high-speed searching applications.
  • It is computer memory that operates like a hardware search engine for search-intensive applications.
  • Associative memory in computer organization is when memory is accessed through content rather than through a specific address.
  • Data stored on CAM can be accessed by searching for the content itself not by a specific address and the memory retrieves the addresses where that content can be found. Because of its parallel nature, CAM is much faster than RAM for searching.

 

Both Statement (I) and Statement (II) are individually true and Statement (II) is the correct explanation of Statement (I)

Important Point:

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.

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.
