Abstract
Methods, systems, and devices for data organization for logical to physical table compression are described. The memory system may identify a region that includes one or more logical addresses associated with discontinuous corresponding physical addresses. The memory system may include a plurality of regions of logical addresses and a plurality of memory cells arranged according to a plurality of physical addresses. The memory system may determine a period of inactivity of access operations on the plurality of memory cells and rearrange, during the period of inactivity, information stored within the discontinuous corresponding physical addresses to be within continuous physical addresses of the plurality of physical addresses.
Claims20
A memory system, comprising:
- one or more memory devices;
- and
- processing circuitry coupled with the one or more memory devices and configured to cause the memory system to:
- identify, within the memory system, a region having one or more logical addresses associated with discontinuous corresponding physical addresses in response to a quantity of the one or more logical addresses associated with the discontinuous corresponding physical addresses satisfying a threshold;
- and
- rearrange, during a period of inactivity of access operations associated with the memory system, information stored within the discontinuous corresponding physical addresses to be within continuous physical addresses of the memory system.
A memory system, comprising:
- one or more memory devices;
- and
- processing circuitry coupled with the one or more memory devices and configured to cause the memory system to:
- identify, within the memory system, a region having one or more logical addresses associated with discontinuous corresponding physical addresses in response to a quantity of the one or more logical addresses associated with the discontinuous corresponding physical addresses satisfying a first threshold;
- and
- rearrange, in accordance with a value of a write amplify factor associated with the region of the memory system failing to satisfy a second threshold, information stored within the discontinuous corresponding physical addresses to be within continuous physical addresses of the memory system.
A method, comprising:
- identifying, within a memory system, a region having one or more logical addresses associated with discontinuous corresponding physical addresses in response to a quantity of the one or more logical addresses associated with the discontinuous corresponding physical addresses satisfying a threshold;
- and
- rearranging, during a period of inactivity of access operations associated with the memory system, information stored within the discontinuous corresponding physical addresses to be within continuous physical addresses of the memory system.
