Abstract
Static read/write memory structures are provided that include predetermined latent-state patterns which can be retrieved with a latent-state retrieve process that differs somewhat from a conventional write process. The patterns are realized with threshold-voltage differences and they significantly enhance flexibility of memory allocation without increasing memory area nor significantly altering conventional read/write processes.
