Reducing power dissipation for solid state disks
First Claim
1. A data processing device comprising a computer, the computer comprising:
- a solid state disk (SSD), comprising;
a primary memory for single level cell storage; and
a secondary memory for multi-level cell storage;
a limited internal battery for supplying power to said computer;
a socket for connecting said computer to an external power supply source;
a detector for indicating that said computer is connected to an external power source;
a processor for transferring data from said primary memory to said secondary memory; and
an SSD controller for deciding whether or not said processor may transfer data from said primary memory to said secondary memory, based on a signal received from said detector.
