MEMORY WITH PARTIAL BANK REFRESH

Abstract:

Memory devices and systems with partial array refresh control over memory regions in a memory array, and associated methods, are disclosed herein. In one embodiment, a memory system includes a memory controller and a memory device operably connected to the memory controller. The memory device includes (i) a memory array having a memory bank with a plurality of memory cells arranged in a plurality of memory row and (ii) circuitry. In some embodiments, the circuitry is configured to disable at least one memory row of the memory bank from receiving refresh commands such that memory cells of the at least one row are not refreshed during refresh operations of the memory device. In some embodiments, the memory controller is configured to track memory rows that include utilized memory cells and/or to write data to the memory rows in accordance with a programming sequence of the memory device.
