What is ROM and how does it work? What are Types of ROM

  1. This was the first ROM. This memory was used in earlier times. But nowadays it is not used at all. In earlier times, this memory used to be quite expensive. Commands and data are already stored in this memory. Nowadays, you will not find this memory anywhere. 2. Programmable Read-Only Memory. Program read-only memory is a memory that you can use only once. If you put data inside this memory.
  2. Due to two reasons, we use the Read Only Memory (ROM) for certain functions with your computer system. Long life Data - All data and programs are stored permanently in the ROM, whether power is getting on or off position. We can remove ROM any time from your computer, and stored it for long time, and it can be replaced but your data doesn't discard still be there. Protection - We know.
  3. The concept of read-only data can also refer to file system permissions. For the British book publisher, see Read-Only Memory (publisher). For other uses, see ROM (disambiguation)
  4. Therefore, larger ROMs use a slightly different architecture, with a set of smaller memory blocks instead of one single large memory block. Each memory block uses approximately the same number of wordlines and bitlines (the applet has 16 wordlines and 8 bitlines). For example, a good size for one memory block might consist of 256 wordlines and 256 bitlines. This means that a 64Kx8 bit ROM would be organized internally as a set of (65536x8) / (256x256) = 8 memory blocks. The top 3 address.
