Abstract: Methods, systems, and devices for variable density storage device are described. A memory system may receive a write command to write data to the memory system. The memory system may write the data to a first set of memory cells of the memory system using a first write operation based on receiving the write command. The first set of memory cells store three or fewer bits of information in a single memory cell. The memory system may identify whether to transfer the data to a second set of memory cells on one or more parameters associated with the data. The second set of memory cells may store more bits of information in a single memory cell than the first set of memory cells. The memory system may transfer the data to the second set of memory cells based on identifying that the data is to be transferred.

Abstract: Methods, systems, and devices for data integrity improvement programming techniques are described. A memory system may be pre-programed with data prior to assembling the memory system, where assembling the memory system may adversely affect data integrity of a portion of the data. The data integrity of the portion of the data may be improved by programming additional data to the memory system or adjusting data characteristics associated with the portion of the data. The memory system may perform a start-up procedure in which the memory system may identify an indication to perform a refresh operation. The memory system may perform a refresh operation using the additional data programmed to the memory system or using the adjusted data characteristics to improve the data integrity of the portion of the data and mitigate performance issues otherwise associated with performing the refresh operation.
