The controller 310 may further include a computer-readable storage medium or “memory” 318 for storing processor-executable instructions, data structures and other information. According to some embodiments, the memory 318 may comprise a dynamic random access memory (“DRAM”) or synchronous dynamic random access memory (“SDRAM”). In further embodiments, the memory 318 may comprise a non-volatile memory, such as read-only memory (“ROM”) and/or FLASH memory. The memory 318 may store a firmware that comprises commands and data necessary for performing the operations of the HDD device 300. According to some embodiments, the memory 318 may store processor-executable instructions that, when executed by the processor 312, perform the routine 200 for performing adaptive spread-spectrum clocking to limit interference in a target band, as described herein.

In addition to the memory 318, the environment may include other computer-readable media storing program modules, data structures and other data described herein for performing adaptive spread-spectrum clocking in the HDD device 300。 It will be appreciated by those skilled in the art that computer-readable media can be any available media that may be accessed by the controller 310 or other computing system, including computer-readable storage media and communications media。 Communications media includes transitory signals。

Computer-readable storage media includes volatile and non-volatile, removable and non-removable storage media implemented in any method or technology for the non-transitory storage of information。 For example, computer-readable storage media includes, but is not limited to, RAM, ROM, erasable programmable ROM (“EPROM”), electrically-erasable programmable ROM (“EEPROM”), FLASH memory or other solid-state memory technology, compact disc ROM (“CD-ROM”), digital versatile disk (“DVD”), high definition DVD (“HD-DVD”), BLU-RAY or other optical storage, magnetic cassettes, magnetic tape, magnetic disk storage or other magnetic storage devices and the like。
