Abstract:
1. A method of assigning locations for two-state data storage in a nonvolatile memory that stores data in both two-state per cell form and multi-state per cell form, comprising: assigning a first physical location for storage of a first unit of data in two-state per cell form in relation to a second physical location of a second unit of data in two-state per cell form according to a separation scheme such that the first physical location and the second physical location are separated by at least a predetermined minimum number of physical locations that store data in multi-state per cell form; and assigning a third physical location for storage of a third unit of data in two-state per cell form according to the separation scheme such that the third physical location is separated from the first physical location by at least the predetermined minimum number of physical locations that store data in multi-state per cell form, and the third physical location is separated from the second physical location by at least the predetermined minimum number of physical locations that store data in multi-state per cell form.
