Techniques for a fragment cursor

A non-transitory computer-readable medium storing code comprising instructions which, when executed by a processor of an electronic device, cause the electronic device to:

• receive a write command associated with a data of a first size;
• detect a cache synchronization operation performed at one or more memory devices of a memory system;
• store the data in a temporary cursor in a flash translation layer of the memory system in response to detecting the cache synchronization operation and based at least in part on the first size of the data, wherein the memory system is associated with the temporary cursor and a second cursor in the flash translation layer of the memory system, the second cursor and the temporary cursor configured to identify a set of memory cells of the one or more memory devices to write the data to, and wherein a mapping unit size of the temporary cursor in the flash translation layer is 8 kilobytes and a mapping unit size of the second cursor in the flash translation layer is 128 kilobytes;
• write data and a quantity of dummy data to the set of memory cells of the one or more memory devices from the temporary cursor based at least in part on detecting the cache synchronization operation and on identifying the set of memory cells, wherein the data written from the temporary cursor and the quantity of dummy data are based at least in part on the first size of the data and the mapping unit size associated with the temporary cursor being a portion of a page;
• and
• cease use of the temporary cursor based at least in part on a completion of the cache synchronization operation.

A method performed by a memory system, comprising:

• receiving a write command associated with a data of a first size;
• detecting a cache synchronization operation performed at one or more memory devices of the memory system;
• storing the data in a temporary cursor in a flash translation layer of the memory system in response to detecting the cache synchronization operation and based at least in part on the first size of the data, wherein the memory system is associated with the temporary cursor and a second cursor in the flash translation layer of the memory system, the second cursor and the temporary cursor configured to identify a set of memory cells of the one or more memory devices to write the data to, and wherein a mapping unit size of the temporary cursor in the flash translation layer is 8 kilobytes and a mapping unit size of the second cursor in the flash translation layer is 128 kilobytes;
• writing the data and a quantity of dummy data to the set of memory cells of the one or more memory devices from the temporary cursor based at least in part on detecting the cache synchronization operation and on identifying the set of memory cells, wherein the data written from the temporary cursor and the quantity of dummy data are based at least in part on the first size of the data and the mapping unit size associated with the temporary cursor being a portion of a page;
• and
• ceasing use of the temporary cursor based at least in part on a completion of the cache synchronization operation.
