Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 0:
1. A method, comprising:
sensing respective data states of memory cells of a group of memory cells of a memory by applying a first voltage pulse to the group of memory cells, wherein the memory further comprises one or more additional memory cells whose data state is indicative whether to refresh the group of memory cells;
sensing, while the first voltage pulse is applied to the group of memory cells, a data state of the one or more additional memory cells by applying a second voltage pulse having a greater magnitude than the first voltage pulse to the one or more additional memory cells; and
applying, to perform a refresh operation on the group of memory cells, a third voltage pulse to those memory cells of the group whose data state is sensed to be in a particular data state in response to the sensed data state of the one or more additional memory cells being different from the particular data state.
