Abstract
A power recovery technique for a data storage device having a non-volatile memory and a control unit is shown. The non-volatile memory is programmed using one-shot programming, wherein N pages are programmed in one round of one-shot programming and N is a number greater than one. A control unit corrects the final page indicator of an active block of the non-volatile memory in a power recovery procedure to cope with a sudden power-off event, to point the final page indicator to a final page among N pages of one round of one-shot programming.

A data storage device, comprising:
- a non-volatile memory, programmed using one-shot programming, wherein N pages are programmed in one round of one-shot programming and N is a number greater than one;
- and
- a control unit, correcting a final page indicator of an active block of the non-volatile memory in a power recovery procedure to cope with a sudden power-off event, to point the final page indicator to a final page among N pages of one round of one-shot programming.
A method for operating a non-volatile memory, comprising:
- programming a non-volatile memory using one-shot programming, wherein N pages are programmed in one round of one-shot programming and N is a number greater than one;
- and
- correcting a final page indicator of an active block of the non-volatile memory in a power recovery procedure to cope with a sudden power-off event, to point the final page indicator to a final page among N pages of one round of one-shot programming.
