Here are some key features along with the definition of PROM:
- One-time programmable: Data can be written only once using a special programmer device that sends high voltage pulses to "burn" fuses or anti-fuses permanently.
- Non-volatile: Retains data even after power loss, but cannot be changed after programming.
- Affordable: Simple design makes it less expensive compared to other rewritable options.
- Used for storing fixed data: Bootloaders, firmware, calibration data, etc., where changeability is not needed.
- Limitations: Not reusable, programming can be risky and irreversible, prone to static electricity damage.

Definition |
PROM, short for Programmable ROM, is a type of memory where the binary information is stored permanently. Unlike RAM, PROM contents remain intact even when power is turned off. |
|
Design Considerations |
- PROMs are designed during the semiconductor manufacturing process. - Transistor layout, width, and placement are crucial. - N-type and P-type semiconductors are used. |
|
Manufacturing Process |
- The manufacturer receives specifications from the customer in tabular form. - Corresponding masks are created to produce the desired output. |
|
Structure |
- PROMs consist of k input lines (for addressing) and n output lines (for data retrieval). - Each address contains n-bit information. |
|
Internal Components |
- Decoder: Converts binary input to decimal output. - OR gates: Use decoder outputs as input. |
|
Classification |
- Mask ROM: Specifications are provided by the customer, and masks are created for desired output. - PROM: User-programmable using fuses or antifuses. - EPROM and EEPROM are variants. |
