PROM is capable to retain their needed data when Computer is getting turn off. On this PROM, data can be written only one time, and it remains there forever. PROM stands for “ Programmable Read Only Memory“. Holding sound data in electronic musical instruments.These types of chips have a software mask which is burned on the chip, when it is designed cycle of semiconductor manufacturing process.
Masked ROMs consist pre-planned program of data otherwise instructions and it is cheaper as well. MROM stands for “ Masked Read Only Memory“, and it is very first ROM was hard-wire devices. There are different types of ROM, and here we will explain each one – If a template is readily available, duplicating the ROM chip is very easy and affordable. It is very expensive stage of ROM manufacture, so it is creating the template. If, any mistake is done during the manufacture process of ROM, then ROM can get unusable.
