1. A method for operating a memory system comprising an array of memory cells and a memory controller and that is connected to a host, comprising: providing a sequential update block in the memory system; receiving a write command from the host to write data in the memory system, the write command comprising a logical address associated with the data; prior to writing the data in the array of memory cells of the memory system, the memory controller determining that the logical address of the data for the write command is designated for storage of a host file management data structure corresponding to the data for the write command; the determination that the logical address of the data for the write command is designated for storage of the host file management data structure causing conversion of the sequential update block to a chaotic update block; and writing the data for the write command to the chaotic update block.
