Abstract: The present invention provides for storage and transmission of digital data by analog media, discrete and continuous, and more particularly to digital data representation for multi-bit data storage and transmission, using means to trade Ns (media noise) with Np (process contributed noise), thus allowing for storage of more bits per memory cell or increase capacity of transmission channel when compared to the amounts attainable by common practice. The storage media may be of any analog type, such as FLASH, RAM (D or S), EPROMS of various types and even used with continuous analog data storage or transmission. Analog storage or transmission is referred here as the general case that embodies the multi bit case. The present invention takes advantage of coding the data for storage by means of “orthogonal” vectors similar to the use of such means in communications.
