The present disclosure generally relates to improved foggy-fine programming. Rather than initially writing to SLC and then later performing a foggy write to QLC with the data read from SLC and then a fine write to QLC with data re-read from SLC, the foggy write to QLC can be performed in parallel to the initial writing to SLC using the same buffer. Once the foggy write to QLC has completed, and the writing to SLC has also completed, the data buffer can be released. The data written in SLC is then be read from SLC and passes through a relocation buffer for the first and only time to then be written using fine programming to QLC. Thus, the data only passes through the relocation buffer one time and the relocation buffer can be freed to usage after only one pass of the data therethrough.
