Segmented Memory Control System for Gaming Devices

1) A segmented memory control system comprising:

• A) A gaming unit having a central processor and a primary memory, the primary memory containing a plurality of primary data sets, each comprising computer code, computer graphics, digitized sound files, or general-purpose data;
• B) At least two reader units operably connected to the central processor, each reader unit capable of reading one of a plurality of removable memory units, each of which contains a plurality of data sets, each data set comprising computer code, graphics, or general-purpose data, the primary memory and the removeable memory units together comprising the memory units;
• C) A means for prioritizing the reader units so that the data sets on the removable memory unit which is inserted into the reader unit with a higher priority takes precedence over the data sets on any removable memory unit which is inserted into the reader unit with a lower priority and the primary data sets in the primary memory, such that the central processor uses the data set with the higher priority during operation of the gaming unit or, if no data set with higher priority exists, the central processor uses a primary data set.
