    摘要: Easily implemented randomization within a flash memory EEPROM reduces the NAND string resistance effect, program disturbs, user read disturbs, and floating gate to floating gate coupling that result from repeated and long term storage of specific data patterns. The randomization may be code generated pseudo randomization or user driven randomization in different embodiments. User driven commands, the timing of which cannot be predicted may be used to trigger and achieve a high level of randomization. Randomly altering the encoding scheme of the data prevents repeated and long term storage of specific data patterns. Even if a user wishes to store the same information for long periods, or to repeatedly store it, it will be randomly encoded with different encoding schemes, and the data pattern will therefore be varied.

    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.
