摘要:
A data storage device for providing zone management optimization may include memories including staging memory areas (e.g., single level cells) and destination memory areas (e.g., quad-level cells). The destination memory areas may include memory regions (e.g., zones). A controller may be configured to receive data from a host system, write the data initially to the staging memory areas, receive a region full indication for a first memory region. In response to receiving the region full indication, the controller may add a first entry corresponding to the first memory region to a double linked list. The controller may select, using a region selection randomization method, a second entry corresponding to a second memory region, and folds a second data to the second memory region. The first data may be associated with the first memory region and the second data may be associated with the second memory region.
