Assignee: MICRON TECHNOLOGY, INC.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 10:
11. A method, comprising:
applying a first voltage pulse to a group of memory cells of a memory to sense a data state of memory cells of the group, wherein:
the memory cells of the group are distributed over a plurality of tiles of the memory; and
the memory further comprises one or more additional memory cells whose data state is indicative of whether to refresh the group of memory cells, wherein the one or more additional memory cells are located in an additional tile of the memory;

applying, while the first voltage pulse is applied to the group of memory cells, a second voltage pulse having a greater magnitude than the first voltage pulse to the one or more additional memory cells to sense a data state of the one or more additional memory cells; and
determining whether to perform a refresh operation on the group of memory cells based on the sensed data state of the one or more additional memory cells.
