An error model with asymmetric/symmetric errors of limited magnitude is a good model for some multi-level flash memories. This talk is about constructions of codes correcting such errors. In the asymmetric case, our results are about codes correcting single  error and codes of length m correcting all errors in m−1 or less positions. In the symmetric case, several constructions of codes correcting a single error are given. In some cases, the codes are perfect or quasi-perfect.
