摘要：Features within an integrated-circuit memory chip enables scrambling or randomization of data stored in an array of nonvolatile memory cells. In one embodiment, randomization within each page helps to control source loading errors during sensing and floating gate to floating gate coupling among neighboring cells. Randomization from page to page helps to reduce program disturbs, user read disturbs, and floating gate to floating gate coupling that result from repeated and long term storage of specific data patterns. In another embodiment, randomization is implemented both within a page and between pages. The scrambling or randomization may be predetermined, or code generated pseudo randomization or user driven randomization in different embodiments. These features are accomplished within the limited resource and budget of the integrated-circuit memory chip.
