In response to a request to store new data at a memory location of a bitwise programmable non-volatile memory, data stored at the memory location of the bitwise programmable memory is sensed. The bits of the sensed data are compared with bits of the new data. An indication of a cost difference is determined between a first burst of bitwise programming operations associated with programming bits of the new data which are different from bits of the sensed data, and a second burst of bitwise programming operations associated with programming bits of a complementary inversion of the new data which are different from bits of the sensed data. One of the first burst of bitwise programming operations or the second burst of bitwise programming operations is executed based on the generated indication of the cost difference.

Method of data management for a bitwise programmable non-volatile memory, and corresponding device

A method can be used for programming a group of memory cells of a non-volatile memory device in a programming window that has a duration longer than a programming duration of a memory cell. The programming window is subdivided into a number of time intervals. A programming profile that was determined by simulation while taking into account a reference criterion is retrieved. The programming profile includes, for each time interval, a maximum number of memory cells that can be triggered for programming within each time interval. The memory device is programmed in the programming window, interval-wise, using the programming profile.
