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.


  • 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 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.
