Abstract
There is disclosed an apparatus and method for reducing power consumption in physiological condition monitors that use a memory data storage device that operates in a high power mode when data is being written to the memory data storage device and operates in a low power mode when inactive. The apparatus comprises: 1) a controller for receiving incoming data to be written to the memory data storage device; and 2) a first low power buffer coupled to the controller. The controller stores the incoming data in the first low power buffer until a predetermined amount of incoming data has been accumulated in the first low power buffer and transfers the accumulated predetermined amount of incoming data to the memory data storage device in a single data transfer.
