A new compact MultiMediaCard (MMC) uses Oki's novel P2ROM production programmed ROM and is compliant with version 3.1 of the standard defined by the MultiMediaCard Association By adopting Oki's P2ROM technology in the MMC, there are no mask charges or additional programming costs, unlike mask ROM-based MMC or Flash-memory-based MMCs

More power from laser modules for WDM systems
Oki Electric has developed a trio of high-power 1480nm pump laser diode modules for WDM (wavelength division multiplexing) optical transmission.
With the advantages of P2ROM, Oki can supply the MMCs on short lead-times after receiving the ROM code data from clients.
"With this MMC based on Oki's unique P2ROM, customers can benefit from the convenience of a shorter turnaround time and no extra charges for mask charges or additional programming costs", said Atsushi Takasugi, Senior Manager, System Memory Marketing Department at Oki Electric.
"This card is suitable for content storage use for equipment such as electronic dictionaries and PDAs.
As it is already available, we plan to actively deploy the P2ROM MMC to our customers worldwide".
MMC is one of the small memory card standards that is widely used for storing and retrieving digital information.
Whereas the footprint is the same as an SD card, the height of the MMC is thinner.
An SD card has 9 pins, 7 of which are the same as the 7 pins in an MMC, which enables an MMC to be read in an SD slot for equipment that does not use the SD card security function.
Basically, there have been two types of MMC: one uses mask ROM and the other uses Flash memory.
With a Flash-memory-based card programming costs occur; and mask charges occur when using a mask ROM-based card.
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.
Furthermore, the time consumed from receiving data to shipment is much shorter than with a mask ROM-based MMC because P2ROM MMC can write data after assembling the MultiMediaCard.
Oki will provide this ROM MultiMediaCard to the worldwide market, targeting content storage applications for equipments such as electronic dictionaries.
