Advanced dynamic disk memory module special operations
First Claim
1. A removable memory module, comprising:
- a volatile memory;
a non-volatile memory; and
a memory module controller, coupled to the volatile memory and the non-volatile memory, that provides address, data, and control interfaces to the volatile memory, the non-volatile memory, and to a host system;
wherein the memory module controller is operable to transfer data from at least one of the volatile memory and the non-volatile memory to a main memory of a host system responsive to the detection of a power state transition in the host system.

Abstract
A memory module including a volatile memory, a non-volatile memory, and a controller that provides address, data, and control interfaces to the memories and to a host system, such as, for example, a personal computer, is operable to interact with the host system so as to provide one or more additional layers in the memory hierarchy of the host system. In one aspect of the present invention the controller operates the volatile memory of the memory module as a cache for the non-volatile memory of the memory module. In another aspect of the present invention data representing one or more software applications and/or one or more data sets are stored in the non-volatile memory of the memory module along with security information such that a host system may quickly launch applications from the memory module rather than from a slower hard disk drive.
