Flash memory card technologies are set to take several big steps forward in the near future. According to the EE Times, imminent developments will enable the storage of full-length movies in cards that can be carried in wallets. Hitachi has announced that it will sell a MultiMediaCard next year with 128 MBytes of memory, capable of storing a minute of movie per MByte. Both Samsung Electronics and Toshiba are preparing 1-Gbit device NAND-type devices.
Flash memory makers are working now to devise a security system so that content can be commercially distributed on memory cards. Hitachi has already proposed a distribution system to the Secure Digital Music Initiative (SDMI) group modeled on Japan’s Keitaide music system. The system distributes public and private keys through servers, mobile-phone memory cards and portable players to encrypt and decrypt license and content data.
