Abstract: A method for storing n bytes in multi-level non-volatile memory cells, including writing and reading of said n bytes. Writing includes the following steps: (a) decomposing each one of such n bytes into eight bits, (b) storing each one of such eight bits into a respective one of such multi-level non-volatile memory cells by utilizing a multi-level technology. Reading includes the following steps: (c) reading contemporaneously each one of such eight bits which belong to each one of said n bytes by sense amplifiers each connected to each one of such multi-level non-volatile memory cells, (d) assembling such eight bits previously read to form each one of such initial n bytes.
