Masked ROM stands for Masked Read-Only Memory. It is a type of memory chip that is created with its contents on it. This means that the data is programmed onto the chip during manufacturing and cannot be altered or reprogrammed afterward. It is a type of read-only memory (ROM) chip that is permanent.
Masked ROMs are different from other ROM categories like PROMs and EPROMs, as the data of it is pre-programmed and cannot be changed. It finds its use in devices and appliances that require constant or unchanging data, such as calculator chips, microwave oven chips, and game console cartridges.
The phrase “Masked ROM” is also used to differentiate it from user-programmable memory like PROMs and FPGAs that allow reprogramming. Masked ROM has masked layers that are used for programming and manufacturing. It is used in the production of high volumes of electronic devices as the cost per unit is low.
Benefits of Masked ROM
Here are some benefits of Masked ROM:
- Low manufacturing cost.
- Low power consumption.
