Abstract

A non-volatile memory system, such as a flash EEPROM system, is disclosed to be divided into a plurality of blocks and each of the blocks into one or more pages, with sectors of data being stored therein that are of a different size than either the pages or blocks. One specific technique packs more sectors into a block than pages provided for that block. Error correction codes and other attribute data for a number of user data sectors are preferably stored together in different pages and blocks than the user data.
