Pre-PMA 2007: In an announcement today Greg Rhine, head of SanDisk's consumer business talked about introducing a 'new category in the middle of the year: a read-only memory card'. This new flash card is using a technology which SanDisk are calling '3D memory' which we presume is based on the Matrix Memory technology which it acquired in 2006 for $250m and we first reported on in 2002 at PMA. These write-once cards are likely to be very cheap but have the advantage of very long term storage (100+ years).
