OVER-SAMPLING READ OPERATION FOR A FLASH MEMORY DEVICE |
摘要 |
A flash memory device and a reading method are provided where memory cells are divided into at least two groups. Memory cells are selected according to a threshold voltage distribution. Data stored in the selected memory cells are detected and the data is latched corresponding to one of the at least two groups according to a first read operation. A second read operation detects and latches data of the memory cells corresponding to another one of the at least two groups. The data is processed through a soft decision algorithm during the second read operation.
