Abstract
A method for data storage includes, for a memory including groups of memory cells, defining a normal mode and a protected mode, wherein in the protected mode a respective analog value of each memory cell remains at all times unambiguously indicative of a respective data value stored in that memory cell. Data is initially stored in the memory using the normal mode. In response to an event, the protected mode is reverted to for at least one of the groups of the memory cells.
