Abstract:
A disk drive is disclosed comprising a head actuated over a disk, a first volatile semiconductor memory (VSM), and a second VSM. When the disk drive is powered on, control circuitry first reads VSM initialization code from the disk, first initializes the first VSM using the VSM initialization code, stores the VSM initialization code in the second VSM, and then enters a power save mode. When exiting the power save mode, the control circuitry second initializes the first VSM using the VSM initialization code stored in the second VSM.
