NON-VOLATILE MEMORY DEVICE AND METHOD THEREFOR |
摘要 |
<p>A method of storing information at a non-volatile memory includes storing a first status bit at a sector header of the memory prior to erasing a sector at the memory. A second status bit is stored after erasing of the sector. Because the erasure of the sector is interleaved with the storage of the status bits, a brownout or other corrupting event during erasure of the record will likely result in a failure to store the second status bit. Therefore, the first and second status bits can be compared to determine if the data was properly erased at the non-volatile memory. Further, multiple status bits can be employed to indicate the status of other memory sectors, so that a difference in the status bits for a particular sector can indicate a brownout or other corrupting event.</p> |
