A new form of modulation coding for page-oriented memories (POM’s) based on parity is introduced. The parity-based codes are evaluated by use of simulated POM data pages. It is illustrated that the proposed parity codes can outperform balanced modulation codes in the presence of fixed-pattern noise and additive white Gaussian noise.
