Abstract
Lifetime extension of a non-volatile semiconductor memory (NVSM) for a data storage device (DSD) includes determining a write amplification factor based on an amount of data previously written to the NVSM and at least one of an amount of data previously requested to be written to the DSD, and an amount of data previously requested to be written to the NVSM. At least a portion of the amount of data to be written to the NVSM is directed or redirected to the disk based on the determined write amplification factor.
