Abstract
A method for data storage includes storing first data in analog memory cells using a first programming operation, which writes to the memory cells respective analog values representing respective bit values of the first data. Second data is stored in the analog memory cells in addition to the first data using a second programming operation, which modifies the respective analog values of the memory cells so as to represent bit value combinations of the first and second data. The first and second programming operations are defined such that, at all times during the second programming operation, the analog value of each memory cell remains unambiguously indicative of the respective bit value of the first data stored in that memory cell.
