Abstract
Flash memory drives and related methods are disclosed that operate to keep frequently written data, which results in frequently erased blocks, in SLC-mimicking MLC flash, and relatively static data in normal MLC flash. A flash drive according to the present disclosure keeps track of the number of times that data for each logical block address (LBA) has been written to the flash memory, and determines whether to store newly received data associated with a particular LBA in SLC-mimicking MLC flash or in normal MLC flash depending on the number of writes that have occurred for that particular LBA. Dynamic allocation can occur between the two types of MLC. Related methods and software are also described.
