US 2026/0064288 A1 · CYCLING OF MEMORY BLOCKS

Abstract

A method for managing wear leveling in a non-volatile memory device, the method initiating, by a memory controller, a block cycling operation on a memory block within the non-volatile memory device. The method includes selecting, by the memory controller, a block cycling mode from a set of block cycling modes. The method also includes outputting, by the memory controller, a block cycling feature command to a local media controller of a memory device that includes the memory block. The method includes executing, by the local media controller, the selected block cycling mode to program the memory block responsive to the block cycling feature command to increase a wear level of the memory block.

A method for managing wear leveling in a non-volatile memory device, the method comprising:

initiating, by a memory controller, a block cycling operation on a memory block within the non-volatile memory device;
selecting, by the memory controller, a block cycling mode from a set of block cycling modes;
outputting, by the memory controller, a block cycling feature command to a local media controller of a memory device that includes the memory block;
and
executing, by the local media controller, the selected block cycling mode to program the memory block responsive to the block cycling feature command to increase a wear level of the memory block.

2 more elements

A system for managing wear leveling in a non-volatile memory device, the system comprising:

a memory device with a block cycling module configured to cycle memory blocks of the memory device;
and
a memory controller programmed to:
identify the memory device as having a memory block in need of cycling to increase a wear level of the memory block;
select a block cycling mode from a set of block cycling modes;
and
output a block cycling feature command to the memory device that identifies the selected block cycling mode;
wherein the memory device executes the selected block cycling mode to program the memory block responsive to the block cycling feature command.

5 more elements

A non-transitory computer-readable medium storing instructions that, when executed by a processor, perform operations for managing wear leveling in a non-volatile memory system, the operations comprising:

identifying a memory device that contains a memory block in need of cycling;
selecting a block cycling mode from a set of block cycling modes;
and
outputting a block cycling feature command to the memory device that identifies the selected mode, wherein the memory device executes the selected block cycling mode to program the memory block responsive to the block cycling feature command to increase a wear level of the memory block.
