Abstract:
Devices and techniques for detecting power loss in NAND memory devices are disclosed herein. A memory controller may calibrate a first read level for a first physical page of a number of physical pages from an initial first read level position to a calibrated first read level position. The first read level may be between a first threshold voltage distribution corresponding to a first logical state of the at least four logical states and a second threshold voltage distribution corresponding to a second logical state of the at least four logical states. Also, the first threshold voltage distribution may be a highest threshold voltage distribution for the first physical page. The memory controller may calibrate a second read level for the first physical page that is lower than the first read level from an initial second read level position to a calibrated first read level position. The memory controller may determine to refresh at least one logical page stored at the first physical page based at least in part on a first read level difference between the initial first read level and the calibrated first read level and a second read level difference between the initial second read level and the calibrated second read level.

Claim (Index 8):
The method of  claim 2 , wherein refreshing memory cells of the at least one logical page comprises copying data stored at the memory cells of the at least one logical page to a new physical page at a block of the flash memory different than a block of the flash memory including the first physical page.
