DYNAMICALLY ADJUSTING READ VOLTAGE IN A NAND FLASH MEMORY
A NAND flash memory device detects the occurrence of Cell Voltage Distribution Disruption Events (CVDDEs), such as a Partial Block Program (PBP) and Program-Read-Immediate (PM), and provides a way to dynamically adjust read voltage to account for CVDDEs. A read command includes extended addressing b...

| description | A NAND flash memory device detects the occurrence of Cell Voltage Distribution Disruption Events (CVDDEs), such as a Partial Block Program (PBP) and Program-Read-Immediate (PM), and provides a way to dynamically adjust read voltage to account for CVDDEs. A read command includes extended addressing bits that are used when a CVDDE has occurred to access registers that indicate an adjustment to read voltage that is needed to accommodate the CVDDE. The read voltage is then dynamically adjusted to accommodate the CVDDE. When the CVDDE is no longer an issue, the read voltage is adjusted to its previous value before the CVDDE. |
