Patent attributes
A variety of applications can include apparatus and/or methods that include tracking data temperatures of logical block addresses for a memory device by operating multiple accumulators by one or more data temperature analyzers to count host writes to ranges of logical block addresses. Data temperature for data written by a host is a measure of how frequently data at a logical block address is overwritten. In various embodiments, tracking can include staggering the start of counting by each of the multiple accumulators to provide subsequent binning of logical block addresses bands into temperature zones, which can achieve better data segregation. Data having a logical block address received from a host can be routed to a block associated with a temperature zone based on the binning provided by the staggered operation of the multiple accumulators by one or more data temperature analyzers. Additional apparatus, systems, and methods are disclosed.
