Abstract
A storage module and method for identifying hot and cold data are provided. The storage module can be removable from a host or can be embedded in a host. In one embodiment, a request to store data in a logical block address (LBA) of a memory of the storage module is received. A physical block associated with the LBA is determined, and it is also determined whether the physical block stores hot or cold data. A last-known open block is then selected, wherein the last-known open block is either hot or cold depending on whether the physical block stores hot or cold data. If space is available in the last-known open block, the data is written to the last-known open block.
