According to an embodiment of the invention, a method and apparatus for computer memory power backup are described. According to one embodiment, a memory system includes a first memory; a second memory coupled to the first memory and to a host, the second memory to transfer data between the first memory and the host; and a backup power source, the backup power source providing power to the first memory and the second memory if a main power source fails.

Computer memory power backup

An optical storage drive having a content-based drive-speed variation capability. The optical storage drive contains a drive speed lookup table that stores drive speeds corresponding to file types or groups of file types. For a given file type, a corresponding coded drive speed is provided to the motor control hardware registers. Based upon the coded drive speed provided the drive voltage is limited to produce a desired drive speed. In one embodiment, the optical storage drive may reduce energy consumption by ascertaining the file type to be read and rotating the optical disk at a reduced speed based upon the file type.
