Abstract
The present invention relates to a method, circuit, and system for performing write journal operations on a bus interface controller board or bus interface controller integrated circuit chip. This is achieved by placed a write journal memory on the board or chip and supplying power to it from an external power source. Preferably, the external power source is a battery. The internal memory may use bus interface controller power when available to prolong battery life.
