Flash memory is a non-volatile computer memory comprised of blocks of cells, wherein each cell can take on q different values or levels. While increasing the cell level is easy, reducing the level of a cell can be accomplished only by erasing an entire block. Since block erasures are highly undesirable, coding schemes—known as floating codes or flash codes—have been designed in order to maximize the number of times that information stored in a flash memory can be written (and re-written) prior… CONTINUE READING
