  • Patent number: 9280421
    Abstract: Providing for single and multi-bit error correction of electronic memory is described herein. As an example, error correction can be accomplished by establishing a suspect region between bit level distributions of a set of analyzed memory cells. The suspect region can define potential error bits for the distributions. If a bit error is detected for the distributions, error correction can first be applied to the potential error bits in the suspect region. By identifying suspected error bits and limiting initial error correction to such identified bits, complexities involved in applying error correction to all bits of the distributions can be mitigated or avoided, improving efficiency of bit error corrections for electronic memory.

  • Patent number: 9276007
    Abstract: A method for fabricating a memory device with a self-aligned trap layer and rounded active region corners is disclosed. In the present invention, an STI process is performed before any of the charge-trapping and top-level layers are formed. Immediately after the STI process, the sharp corners of the active regions are exposed. Because these sharp corners are exposed at this time, they are available to be rounded through any number of known rounding techniques. Rounding the corners improves the performance characteristics of the memory device. Subsequent to the rounding process, the charge-trapping structure and other layers can be formed by a self-aligned process.
