Abstract
Methods, systems, and devices for techniques for memory system refresh are described. In some cases, a memory system may prioritize refreshing blocks of memory cells containing control information for the file system of the memory system. For example, the memory system may identify a block of memory cells containing control information and adjust an error threshold for refreshing the blocks of memory cells to be lower than an error threshold for refreshing the blocks of memory cells containing data other than control information. Additionally or alternatively, the memory system may perform a refresh control operation for the block of memory cells with a higher frequency (e.g., more frequently) than for other blocks of memory cells.
Claims25
A method, comprising:
- identifying whether a block of memory cells of a memory system comprises control information associated with a file system of the memory system;
- adjusting a threshold associated with an error control operation of the block of memory cells from a first threshold to a second threshold based at least in part on identifying that the block of memory cells comprises the control information;
- and
- performing a refresh control operation on the block of memory cells based at least in part on the second threshold.
A memory system, comprising:
- processing circuitry associated with one or more memory devices, wherein the processing circuitry is configured to cause the memory system to:
- identify whether a block of memory cells of the memory system comprises control information associated with a file system of the memory system;
- adjust a threshold associated with an error control operation of the block of memory cells from a first threshold to a second threshold based at least in part on identifying that the block of memory cells comprises the control information;
- and
- perform a refresh control operation on the block of memory cells based at least in part on the second threshold.
A non-transitory computer-readable medium storing code, the code comprising instructions executable by a processor to:
- identify whether a block of memory cells of a memory system comprises control information associated with a file system of the memory system;
- adjust a threshold associated with an error control operation of the block of memory cells from a first threshold to a second threshold based at least in part on identifying that the block of memory cells comprises the control information;
- and
- perform a refresh control operation on the block of memory cells based at least in part on the second threshold.
