Soft error protection in individual memory devices |
摘要 |
Techniques are disclosed for minimizing the effects of soft errors associated with memory devices that are individually accessible. By way of example, a method of organizing a column in a memory array of a memory device protected by an error correction code comprises the step of maximizing a distance of the error correction code by maximizing a physical distance between memory bits associated with a memory line within the column protected by the error correction code. Other soft error protection techniques may include use of a feed forward error correction code or use of a memory operation (e.g., read or write operation) suppress and retry approach.
