 ROM: vita, morte e miracoli
Le ROM, o Read Only Memory, sono memorie a sola lettura ad accesso casuale nelle quali i dati sono memorizzati in forma permanente ovvero, a differenza delle memorie volatili, i dati restano memorizzati anche in assenza di alimentazione.
MASK ROM: sono programmate direttamente dal costruttore seguendo un procedimento di tipo "fotografico" in cui si usa una maschera (da cui il nome) per il drogaggio delle diverse zone del chip.
Si cancellano tramite impulsi elettrici e permettono la riprogrammazione all'interno del sistema dove sono utilizzate, in particolar modo hanno la possibilità di essere cancellate e riprogrammate per settori, quindi la memoria non deve essere cancellata completamente per effettuare, per esempio, un aggiornamento.

Mask ROM's are consequently used in systems such as control memories in microprogram-control-type computers, microcomputer program memories, and for various kinds of terminals.
Subsequent completion of the mask ROM requires only the formation of a surface protective layer on which wiring is formed and the formation of bonding pad.
In this type of mask ROM, the establishment in the programming process of enhancement characteristics or depletion characteristics for each MOS transistor memory cell must be followed by many processes, including a gate-forming process, before the mask ROM is completed, as mentioned previously.

In mask ROM, a mask is used in the wafer process stage to write program code and data supplied by the equipment manufacturer.
Mask ROMs, however, are usually made with 0.25micron semiconductor manufacturing process technology, while the P2ROM is a generation ahead at 0.2micron (Fig 3b).
According to a source at the Japan office of Macronix International Co, Ltd of Taiwan, "A mask costs about a million yen for 0.18micron rule, three million for 0.13micron, and easily over ten million for 0.09micron." This ten million yen development cost for mask ROM is simply impossible for most equipment manufacturers.

Mask ROM refers to a kind of ROM whose contents are programmed by the IC manufacturer.
Since the process is costly, mask ROM is used when the needed volume is high and it is absolutely certain that the contents will not change.
The main advantage of mask ROM is its cost, since it is significantly cheaper than other kinds of ROM, but if an error in the data/code is found, the entire batch must be thrown away.

Although the majority of the circuitry in a Mask ROM chip is based on a relatively standard design, we often incorporate customer design specifications into application-specific portions of the circuitry during the manufacturing process.
We began to manufacture Mask ROMs at Fab II at line widths of 0.18 micron from the second half of 2000 and successfully migrated to 0.15 micron process technology for both Flash and Mask ROM in the fourth quarter of 2002.

Our Mask ROM circuits are perfect for programs where order quantities are higher than 5,000, for audio of 60-seconds or longer, or for shorter audio lengths where order quantities exceed 10,000 or 15,000 units.
If your orders are for small quantities but you plan on re-ordering the same audio, a Mask ROM might be appropriate.
Mask ROMs are available in nominal audio lengths from 3 to 255 seconds.

Basically, there have been two types of MMC: one type that uses mask ROM and the other that uses flash memory.
However, using Oki's original P2ROM that does not use a mask when programming user data, this MMC needs no additional charge for programming data because content programming is done within the regular process.
Unlike mask ROM that is programmed with a mask during the wafer process, P2ROM can program data during the final test process, which significantly shortens the turn-around-time.
