Abstract: Memory devices, systems including memory devices, and methods of operating memory devices in which multiple counters are provided to permit memory refresh commands greater freedom in targeting subsets of the memory device for data refresh operations.

Abstract: A memory device is provided. The memory device comprises a memory array and circuitry configured to determine one or more settings for the memory array corresponding to a powered-on state of the memory device, to store the one or more settings in a non-volatile memory location, and in response to returning to the powered-on state from a reduced-power state, to read the one or more settings from the non-volatile memory location.

Abstract: Memory devices, system, and methods for operating the same are provided. The memory device can comprise a non-volatile memory array and control circuitry. The control circuitry can be configured to store a value corresponding to a number of activate commands received at the memory device, update the value in response to receiving an activate command received from a host device, and trigger, in response to the value exceeding a predetermined threshold, a remedial action performed by the memory device. The control circuitry can be further configured to store a second value corresponding to a number of refresh operations performed by the memory device, update the second value in response to performing a refresh operation, and trigger, in response to the value exceeding a second predetermined threshold, a second remedial action performed by the memory device.

Abstract: Memory devices and methods of operating memory devices in which refresh management operations can be scheduled on an as-needed basis for those memory portions where activity (e.g., activations in excess of a predetermined threshold) warrants a refresh management operation are disclosed. In one embodiment, an apparatus comprises a memory including a memory location, and circuitry configured to determine a count corresponding to a number of activations at the memory location, to schedule a refresh management operation for the memory location in response to the count exceeding a first predetermined threshold, and to decrease the count by an amount corresponding to the first predetermined threshold in response to executing the scheduled refresh management operation. The circuitry may be further configured to disallow, in response to determining that the count has reached a maximum permitted value, further activations at the memory location until after the count has been decreased.

Abstract: The present disclosure includes apparatuses and methods related to data movement operations in non-volatile memory. An example apparatus can comprise an array of non-volatile memory cells including a plurality of sections each with a plurality of rows and a controller configured to move data stored in a first portion of the array from a first row of a first section to a second row of the first section and move data stored in a second portion of the array from a second section to the first to create an open row in the second section in response to data from a particular number of portions of memory cells in the first section being moved within the first section.
