Abstract
Memory units and computer systems are provided. The computer systems include a memory unit. The memory unit includes a stable storage unit, an unstable storage unit, and a controller. The unstable storage unit stores pending write operations for the stable storage unit. The controller is configured to determine the locations in the unstable storage that store the pending write information and to selectively write the pending write operations to the stable storage unit when power to the memory unit is interrupted.
Claims22
A memory unit comprising:
- a stable storage unit;
- an unstable storage unit that stores pending write operations for the stable storage unit;
- and
- a controller configured to determine the locations in the unstable storage that store the pending write information and to selectively write the pending write operations to the stable storage unit when power to the memory unit is interrupted.

A memory unit comprising:
- a stable storage unit;
- a volatile cache that stores pending write operations for the stable storage unit;
- a controller configured to determine the locations in the unstable storage that store the pending write information and to selectively write the pending write operations to the stable storage unit when power to the memory unit is interrupted;
- and
- an energy storage device electrically coupled with the controller to provide backup power when main power to the memory unit is interrupted.
