An address transition detection interface is disclosed for a sensing circuit that determines a state of a memory cell having n possible states, where n is greater than 2, and wherein no decoding logic is required to translate outputs of comparators into binary bits. In the case where n is 4, the sensing...http://www.google.es/patents/US5594691?utm_source=gb-gplus-sharePatente US5594691 - Address transition detection sensing interface for flash memory having multi-bit cells
